We’ve now moved past the mid-winter point (Groundhog’s Day) and are heading towards spring, even though our recent blizzards don’t make it seem that way. We’ve got some add-ons and some news here at eMathInstruction, so let’s get to it.

For this month’s Common Core Algebra I Add-Ons we have three new additions. We start with a worksheet that gives students extra practice simplifying square roots. This is a nice worksheet if you just feel kids need extra practice on this skill. From there we move on to a Form B Formative Assessment for Unit 9 (Roots and Irrational Numbers). Our last add-on for the month is a mid-unit quiz for Unit 10 on Statistics.

We have some nice materials for our Common Core Algebra II Add-Ons this month. They are all about Unit 11 – The Circular Functions (i.e. the Trig Functions). First we bring you a mid-unit quiz that covers the first 5 lessons and will give teachers a good sense if students are understanding the basic concepts of these non-algebraic functions. Next we have a wonderful modeling activity where students use sinusoidal functions to model the length of daylight in both Poughkeepsie, New York, and Brisbane, Australia. This graphing activity uses the online graphing calculator Desmos, so there is no need for you to enter data by hand or into any calculators. Students just click on a link and are taken immediately to the data. Finally, we have a Form B Formative Assessment for Unit 11.

For the Algebra 2 and Trigonometry Add-Ons, we bring two solid Formative Unit Assessments. The first is for Unit 10 – Exponential and Logarithmic Functions. This is a challenging assessment that will really let teachers see how much students have learned about these challenging topics. We then bring you a Formative Assessment for Unit 11 – Probability. Students will be challenged to deal with combinations, permutations, and binomial probability. Fun!

Besides add-ons, we have news on other fronts. We have experienced a great deal of growth in our website traffic in the last year. So, in the next week we will be switching hosting services to one that can carry all of the traffic easily. That might cause a few hours of our site being out, but we will attempt to do that in the overnight hours on some weekend night when hopefully no one is actually using our site.

Common Core Geometry is coming along nicely. We are done with our first draft of the answer key, which also means we are done with our second round of editing on the book itself. We plan to have Common Core Geometry workbooks and answer key subscriptions ready for quote in mid-March and ready for sale around Memorial Day. We have just begun to work on the videos and will begin to release them as we get them done and edited.  We may be taking our time on these and because of that may not have the QR codes on the first edition of our workbooks. But, if that is the case, we will certainly publish a hyperlinked table of contents and will always have the links handy on our website.

We continue to work on a Spanish language version of Common Core Algebra I. We believe we will be ready to sell this for the 2017-2018 school year (it is done in its first draft).

Well, that’s about it for now. As always, contact us if you have suggestions for add-ons or if you have any questions. You can always reach me at: Kirk@emathinstruction.com.

It’s January in upstate New York, which means it is really, really cold with no end of winter in site. For our friends in Arizona and other warm climates, now is the time to really enjoy how great it is not to have radical season change. We are quickly heading towards the mid-year point here and we have eMathInstruction news to report and add-ons to add on.

Let’s get to those add-ons. First up are the Common Core Algebra I Add-Ons. We start with monster packet of factoring questions. I’ve always found it useful to have a day where I have kids practice on all of the major types of factoring and that’s exactly what this packet does. It is arrange by difficulty level, although with factoring that can vary. We then move on to Unit #8, on quadratics, with a Trinomial Perfect Square Warm-Up worksheet. We created this warm-up to give students who struggle with factoring a bit of practice with factoring perfect square trinomial before they start the process of completing the square. Finally, we have a Unit #8 Formative Assessment Form B exam. Again, these make-ups have been the most popular add-on so far so we will continue to crank them out for the course.

Moving on to the Common Core Algebra II Add-Ons, we have lots to offer this month. This month the add-ons are all centered on the length Unit #10 – Polynomial and Rational Functions. First up is a mid-unit quiz that assesses knowledge through Lesson #7. Next we have a lesson and homework set on the Sum and Difference of Perfect Cubes. This is likely different from what you might expect. I find memorizing the formulas for these two polynomial identities less than useful, so I emphasize factoring these by first finding a zero, then a factor, and then using Polynomial Long Division to finish the factoring. We of course offer up for this month a Unit #10 Formative Assessment Form B for all of those kids who miss the first one or just if you want to use a different one from the original. Lastly, we have a great graphing activity called the Polynomial Challenge. I put this out last year, but cleaned it up and made it better for this add-on. The activity uses Desmos and has kids find the equations for over 20 polynomial graphs. We did this at Arlington last year and it worked great. It’s hard to imagine any student working through this and then not understanding the connections between the zeroes of a polynomial and its graph.

Lastly we bring you the Algebra 2 with Trigonometry Add-Ons. As we promised at the beginning of the year, our emphasis for this year on Algebra 2 with Trigonometry was to  create and publish formative assessments for the course. For this month we are adding a Unit #8 Formative Assessment (Trigonometric Equations and Identities) and a Unit #9 Formative Assessment (Trigonometric Applications). These are challenging tests and will truly assess how well students have mastered the trigonometry in this course.

We continue to move along on many other fronts at eMath. We are on the verge of being listed on the New York City ShopDOE/FAMIS system. This should help all of the great schools in New York City to more easily order our products. We are also moving ahead on the Common Core Geometry Answer Key with approximately 70% of it completed in its first form. It should be ready for quoting purposes in February and ordering by Memorial Day weekend for next year. It will likely be a less costly subscription that our others because we plan on adding the unit reviews and assessments next year as add-ons. We will start the Geometry videos in mid-February and will likely be putting them up on YouTube as soon as we get each of them done and edited. We have some surprises coming with these videos, so watch for them.

That’s it for now. Enjoy the rest of your January and early February. Good luck to all the schools that will be administering January Regents exams here in New York. May your students think clearly (and get good night’s sleep the nigh before). As always, if you have any questions, please send them my way at: Kirk@emathinstruction.com.

Well, it definitely feels and looks a lot like winter here in Red Hook, New York. It’s cold and snowy outside, but things are continuing to heat up at eMathInstruction. We’ve got a lot of news, including a new round of add-ons and updates on Common Core Geometry. Let me get right to it.

In our latest Common Core Algebra I Add-Ons, we continue to crank out the Form B assessments based on the positive feedback we’ve been getting. We’ve heard teachers will give both tests during a class period or even slice and dice them up together. So, we do plan to continue to come out with these each month. For this month, we have both a Unit #6 and Unit #7 Form B assessment. As well, we also published a very basic lesson and homework set on percents (creatively entitled Percent Warm-Up). I’ve found over the years that many students are not ready for high school lessons on percents without a basic reminder of what they mean and how they related to ratios and proportions.

For Common Core Algebra II Add-Ons, its much of the same.  We have new Form B assessments for both Units #8 and #9. We have been trying to make these as close to possible to the original tests so that teachers can truly use them as either makeups or for the full class in a mix-it up scenario. We also thought, since we were at Unit #8, to put together a nice set of review problems for the course as a whole. So, we came up with a six page Mid-Course Review problem set. This set certainly doesn’t cover every important problem or topic, because then it would be 20 pages, but it is a nice sampling of problems. We thought it would be ideal for either a Winter Break assignment or perhaps even during January Regents week, depending on where you are in the course.

Finally, there are the Algebra 2 with Trigonometry Add-Ons.  It’s all about Unit #7 this month. This is a long unit that begins a three unit swing through trigonometry. Because of the length of the unit, we’ve included a mid-unit quiz and a Formative assessment for it. But, the fun add-on for this month is a graphing activity on Desmos where students model the length of daylight as a function of the day of the year in Poughkeepsie, New York and Brisbane, Australia. I love Desmos for data modeling because I enter the data once and only once and then simply give students a link to the Desmos page so they can try to fit the data. Don’t worry, though. If you want to use this activity, and it is a really fun one, you don’t even need to enter the data. I’ve already done it for you.

The big news for this month is that Common Core Geometry is done and now in its Beta testing version. That’s just my way of saying that the entire rough draft is done and posted online. Here’s how the table of contents is looking:

I’ve written about the first draft of it here so I don’t bore you more with details. I’m now hard at work on the answer key for Geometry. We are working on a new recording space for the Geometry videos and will likely begin in early February. I’m very much looking forward to getting back to that side of things, although both the text and even the answer key have been a lot of fun.

O.k. That’s it for now. I need to add more logs to the fire and get back to working on that Geo answer key. Thank you to everyone for feedback. And I’d like to thank everyone who has given our curriculum a chance and has supported us. As always, let me know if you have any thoughts: Kirk@emathinstruction.com.

Have a safe and happy holiday season!!!

Now that we’ve made it past Halloween and the election, it’s time for Thanksgiving and the winter holidays. As always, we’ve been busy here at eMathInstruction with Common Core Geometry, Course Add-Ons, and Conferences left and right. I’ll discuss each in turn, but let’s get right to the add-ons.

This month in our Common Core Algebra I Add-Ons we have our latest installment of Form B exams. We now have one posted for Unit #4 (Linear Functions) and Unit #5 (Linear Systems). We’ve gotten a lot of feedback from teachers about how much they enjoy having additional exams that mirror the originals. Perhaps in 2017-2018 we will start with the Form C exams. Who knows? As well as these resources, we also have an additional problem set on real world applications of Linear Systems. You can never have too many Linear Systems Word problems to choose from, so it’s great to have an additional set for those students who are struggling or just extra practice for all of your students.

We continue to follow the assessment theme in our Common Core Algebra II Add-Ons this month by publishing a Form B exam for both Unit #6 (Quadratic Functions) and Unit #7 (Transformations). Both exams mirror the original by assessing the same standards in a given problem while modifying it enough to be able to be used as a makeup exam or even a redo. As well as these assessments, we have also created another Desmos graphing activity. This activity on Transforming Functions should be done at the end of Unit #7 and will solidify student understanding of how modifying a function’s equation can change its graph. This would be a great activity to do on the day before a long break (hint, hint).

Finally, for Algebra 2 and Trigonometry Add-Ons, we supplied two additional assessments. As we’ve noted in previous newsletters, one of the big gaps in our Algebra 2 with Trigonometry curriculum is a lack of Unit assessments. This month we add a full unit quiz for Unit #5 (Complex Numbers) and a Formative Assessment for Unit #6 (Polynomial and Rational Functions). That second assessment is a beast. We highly recommend taking a look at it and thinking about the amount of time it will take your students to complete.

In other exciting news, we are coming closer and closer to be finished with Common Core Geometry, at least in its Beta Version. We now have 9 out of 10 units posted, with our latest unit, Circle Geometry, posted just this morning along with the add-ons. Check out all of the units by going over to our Courses page:

As always, we love when teachers test our courses in these rough versions and let us know about issues, both large and small, that they see. There truly is nothing like having lots of eyes on a curriculum to help remove the bugs. We plan on finishing the Beta version by Winter break and then begin on the answer key and videos. We hope to be able to sell books and answer key subscriptions in late March of 2017.

Finally, we are now in the middle of conference season. I’ve presented now up in Albany, down in Rye Brook, and soon in New York City. This week alone I will be flying out to Phoenix, Arizona, then back on a red-eye in order to present down in Hunter College to AMTNYC. By the time Thanksgiving arrives, I’ll just about be ready to sleep for a week. I’m sure many of my teacher friends will be ready as well.

Have a safe and happy Thanksgiving break everyone. Five days off will feel great. May your stomachs be full and your naps long as the days grow short again. Remember, you can always contact me with questions and suggestions at: Kirk@emathinstruction.com.

Here in the great Northeast, the leaves have changed and the days are getting colder. Since I last wrote, I’ve been hard at work on Common Core Geometry and the latest round of add-ons. Speaking of which, we just put them up on the site. Remember, links to them are at the bottom of each course page. You can also click on any of the blue links below to be taken directly to the add-on pages.  As always, we base what we create on feedback we get, especially on Facebook and other social media. So, let us know where you want the emphasis to be placed.

For Common Core Algebra I Add-Ons this month, we have a Form B for the Unit #3 Assessment, a Unit #4 Progress Quiz, and a worksheet on turning visual patterns into arithmetic sequences. We’ve heard from a lot of you that you want more assessment, especially make-ups/Form B’s. With all of our Form B assessments, we attempt to make them mirror the original so that you have as much equity and cross comparison as possible. Unit #4 on Linear Functions and Arithmetic Sequences is a long unit. So, we created a mid-unit quiz that assesses through Lesson #7. We even included a Form A and Form B of the quiz. Finally, we’ve all seen kids struggle on standardized exams turning visual patterns into arithmetic sequence rules. So, I created a short worksheet with a bunch of these patterns for you to use for practice with your kids. This is especially good for a sub day or other time you need a quick resource.

For Common Core Algebra II Add-Ons this month, it is much the same as with CC Alg I. We created a Form B make-up assessment for both Unit #4 and Unit# 5. Unit #4, of course, is that beastly long Exponential and Log unit, so it may help a lot to have a make-up for that one. Of course it also doesn’t hurt to have a make-up for Unit #5 (Sequences and Series) either. We also added a new lesson! No video yet, but we now introduce Unit #6.Lesson #5.5.Using Structure to Factor. This was a lesson we felt we had to create based on some of the very complex factoring we’ve seen on the first two Common Core Algebra II Regents exams in New York State. I must say, I love this lesson and this factoring. It’s all mixed up and forces kids to think about larger patters with gcf’s, difference of perfect squares, and trinomials. Check it out if you have this subscription.

Finally, for Algebra 2 with Trigonometry Add-Ons, we offer two new Formative Assessments for Units 3 and 4. We never did write unit assessments for Algebra 2 and Trigonometry (our first course). So, that’s going to be a focus of the Algebra 2 with Trigonometry Add-Ons this year. We want to make sure that teachers who are using that course have access to quality assessments.

So, besides the add-ons, I’ve obviously been busy, busy, busy with writing Common Core Geometry and working on technical issues with our website. Since the last eMath Newsletter, we’ve put up three more units. Check out all of the materials we have up now under the courses tab:

Only three more units to go!!! We are trying to get the rough draft of the entire curriculum done by the beginning of winter break. That’s when we will start production on the answer key and on the videos. They will go hand in hand and I will likely post videos to YouTube by the unit.  I suspect we will have Unit 8, on Right Triangle Trigonometry, posted some time next week. The last two units, on Circle Geometry and Three Dimensional Geometry, will take a bit longer to get done and up because it’s…

Conference Season!!! I will be in Rye on November 10th through the 12th for the AMTNYS Fall conference. I’ll be showing teachers how to create interactive lessons on Desmos to address Common Core Algebra standards. I’ll also be showing teachers how to use our new Efofex software line to create graphics for all sorts of fields (geometry, algebra, statistics, etcetera). Don’t miss out. On November 19th, I’ll be at the ATMNYC conference at Hunter College. I’m going to be talking about the thinking that goes into the new emphasis on transformations in Common Core Geometry. I’m really excited about the talk as I’ve never had a chance to speak to teachers about H. Wu’s work on rigid motions and how it leads to congruence in geometry.

O.k. Enough for now. As always, email me with questions, suggestions, or any issues you are having, Kirk@emathinstruction.com.  Have a great rest of your October and a safe and happy Halloween.

As Labor Day Weekend starts to fade in our rear view mirror and mid-September approaches, it’s time for the monthly eMath Newsletter. I’ve been really busy since mid-August, mostly filling orders, answering lots of questions, and helping folks troubleshoot our new online Answer Key Subscription Service. My apologies for those who had trouble setting up their accounts. As always, email me if you have any issues.

I’ve also been working hard in the last few weeks on the latest round of add-ons that come with our Teacher Plus Subscriptions. I just posted them on the site, so those that have that access (and those that don’t) should go over and check them out. As usual, I wanted to tell you a little about them in the newsletter.

For Common Core Algebra I (our most popular course), we have three/four new selections. We came out with a mid-unit progress quiz for Unit #2. We put up a Form A and Form B for your convenience. We created a worksheet that gives students more practice with linear word problems. This one should definitely be done after you have done Lesson #7 in Unit #2. It’s a really good sheet that can be used as extra credit or just more practice for struggling learners. Finally, we created a small worksheet to prepare kids for inequality work later in Unit #2. This sheet is great for a two year CC Algebra I course where kids have a really hard time comparing two numbers using the greater than and less than operators.

For Common Core Algebra II, I started off with one of my favorites, a Desmos Classroom Activity on Forms of a Line. Students are supposed to come out of Common Core Geometry with some exposure to both the slope-intercept and point-slope form of a line. This Desmos Activity allows students to practice in an interactive way with equations of lines in both forms. It could be used as extra credit, extra practice, or even to replace Unit #3.Lesson #3. Don’t worry if you’ve never done a Classroom Activity on Desmos. I’ve also created a detailed Teacher Direction sheet. Email me if you still have questions.

I’ve also created a mid-unit quiz for Unit #4 of Common Core Algebra II. This is a mammoth unit, so I thought having a quiz that covered the topics from the first seven lessons would be helpful. It’s not a long quiz, but it assesses all of the fundamentals of exponential functions. Finally, I added a brand new lesson to Common Core Algebra II on the asymptotes of exponential and logarithmic functions. The term asymptote does not arise in the Common Core Algebra II PARCC standards, but New York State put it on their June Regents examination in CC Alg II, so I thought it might make sense to have a lesson on these important graphical features. No video, yet!

Finally, Algebra 2 with Trigonometry. I feel like this is sometimes the forgotten child of the three courses. It has been all but phased out in New York State, and, yet, plenty of schools still use our text. We love the course and recognize the important differences and similarities between it and Common Core Algebra II. For this month, I’ve added three new resources for the course. First, I have a full (but somewhat short) Unit #2 Quiz (on linear functions). I also included a Unit #3 Mid-Unit progress quiz. Unit #3 is a long unit on quadratic functions and their algebra, so I thought it appropriate to see what kids know after the first eight lessons. Finally, I included a brand-new lesson in Algebra 2 with Trig on Factoring by Grouping. This lesson was long overdue.

Now that I’ve gotten the add-ons out of the way, let’s talk about Common Core Geometry. I’ve really taken a pause on that since late August. I’ve simply been too busy with running the business and writing the add-ons, but now I should be able to get back to writing it. I’m in the middle of Unit 5 right now (the first four units have been posted) and hope to have it finished by the end of next week. I’ll post all of the first draft pdf files at that point. I’m going to continue to write units and maybe record some videos (just to try out some new tech that I have). My goal is to be done with all lessons and homework sets in first draft form by December winter break. The answer key and videos will take some time as well, but, with some hard work, I will hopefully be done with it all by late winter/early spring. Only then will we have Common Core Geometry subscriptions and workbooks to sell at eMathInstruction.

For those of you already working with the curriculum, I image some will be almost done with Unit #1 soon. Unit #2 in CC Geo is on transformations and many of the lessons involve the use of tracing paper. We create our own because we couldn’t find anything on the market we liked. I’m hoping that by Monday of next week (9/19/16) we will have it on our site for sale. It will come in 50 sheet spiral packs that students can rip sheets from (for $5 each) or in stacks of 500 (for$20 each). Here are a few pictures of the tracing paper:

Finally, a note on  our new software products from Efofex. There’s been a lot of interest in the programs given their ease of use. I was talking to a teacher on the phone about Geometry just a couple of days ago and he was bemoaning how difficult making diagrams for geo can be. Efofex MathPack, one of the packages we sell, makes creating these things so easy that I’m chomping at the bit to get back to writing it all. I just wish the software would have been around back in 2005 when I first started work with the Arlington Algebra Project. Imagine how long this would take using the standards graphics on MS Word?

And my own least favorite graphs to draw, exponentials:

If you are interested in seeing what the Efofex software can do, try downloading a free 30 day trial of it. No muss, no fuss, and no spam if you decide you don’t like it. It just stops working. If you have any questions about it, don’t hesitate to contact me.

O.k. So, that’s about it for September. I hope that everyone’s school year is starting off well and the temperatures are cooling everywhere (I’m sure Phoenix is still quite hot my Arizona friends). I’ll be working hard on Common Core Geometry and more add-ons in the next month. Tune in for all the updates in the October newsletter. As always, contact me via email if you have questions or suggestions: Kirk@emathinstruction.com.

Hello my math teacher friends. To those on vacation still, I hope your August is relaxing and Labor Day weekend doesn’t arrive too soon. For those of you back in classes, I hope the beginning of the school year is going well and you are starting to get to know all of your little angels (or angles :-).

We are doing a ton over at eMathInstruction. Within days (or even hours), we will be relaunching our website and coming out with some very exciting new software by an awesome company called Efofex. But, more on that in another post coming soon. I’ll also be posting preliminary Common Core Geometry materials. But, that is also deserving of its own post.

The relaunch will allow users more control over their Membership pages. You will be able to add additional subscription codes as well as other features. The launch will occur at night, so hopefully none of you will be stuck without our site in the middle of your class day.

We just published our first round of Course Add-Ons. These are the additional curricular items that come with the Teacher Plus subscription to our courses. Many of these curricular resources were created based on excellent feedback that I received in a Facebook post. I’ll keep doing these posts to get more ideas. Feel free to add your voice to the conversation. You can check out what I’ve created under the Course pages, but I’ll give you a little description here.

In Common Core Algebra I, I decided to make up a mid-unit quiz and created two forms of it so that you have a back-up for that student who is already absent after only 6 days of school. The quiz covers through Lesson 6 (Seeing Structure in Expressions). I also created a Unit 1 Skill Building set. This set of problems covers through Lesson 5 and is good for the student who needs more practice identifying properties and simplifying simple linear expressions. Finally, I created a Warm-Up lesson on solving one and two-step equations. This is particularly good to assign to students or use in class before beginning Unit 2. Students are expected to be fluent in linear equation solving after 8th grade Common Core, but we know that many of them will need this basic brush-up before moving on to solve more challenging equations.

Now, for Common Core Algebra II, I’ve created three new resources to start off the year. I thought it would be good to have a Form B of the Unit #1 Formative Assessment. This test exactly mirrors the one that is under Common Core Algebra II Unit Assessments. It could be used as a make-up, a re-take, or even if you wanted to pass out two forms of the test at the same time (wandering eyes…). Besides the test, I also created two additional curriculum resources. One of these is an additional set of problems to help students work with interpreting graphs of functions. We all know how students can struggle with reading graphs, especially when it comes to functions. This worksheet could be used toward the end of Unit 2 in order to reinforce graphical ideas. I also created an additional set of problems on Inverse Functions. Although it is early in the course, students can easily become confused about inverses and this set of problems hits all the main ideas.

Finally, for Algebra 2 and Trigonometry, I modified the two resources on Graphs of Functions and Inverses of Functions to fit the emphases and timeline of Algebra 2 with Trigonometry (see above paragraph). As well, I created a Unit quiz for Unit #1 that can be used as a take-home or a short in-class quiz.

Every month, around the middle of the month, until June, I will be putting out the eMath Newsletter where I’ll release the add-ons and discuss the issues of the day. I’ll always make sure to announce the Newsletter on our  and encourage our Members to give us comments there in terms of what resources they’d like to see us create next month.
