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.
