Ever since I wrote Common Core Algebra I, I’ve had numerous discussions with math teachers around the country who weighed in on the subject of intervals of increase and decrease of functions. In my answer key, I often include the x-coordinates of the turning points in the intervals, although I’m not entirely consistent on it. Now, I’ve had folks email me clearly upset that I’ve included the x-values of turning points in the intervals. Their… Read more »

A Little Halloween Problem – CC Alg I and Alg II
Posted onSo, I was driving around with my son Maxwell (Max) and we were discussing giant pumpkins. The whole family loves carving pumpkins each year and we had just seen a television show about the giant squash species. So, he posed the question: “How big do you think the largest pumpkin in the world is?” Well, that made me think of many math problems, from the obvious relationship between the diameter or circumference and the weight.… Read more »
History of CC Algebra I Questions – by Christopher Desmond and the Nottingham Teachers
Posted onSo, Chris Desmond from Nottingham High School in Syracuse, where I did my formative student teaching many, many years ago, has done an analysis with his fellow teachers of all of the questions that have been asked so far on the Common Core Algebra I exam given in New York state. Their analysis comes in the form of an Excel spreadsheet where they’ve analyzed the percent of questions that are tied to a given CC… Read more »

CC Alg I Calculator Directions for Statistics – by Brett Widman
Posted onBrett Widman was kind enough to put together a document that has step by step directions for pretty much all of the statistical work that we do on the TI calculators for Common Core Algebra I. He snipped the instructions from a user manual and then placed it in one handy Word document. This gives a nice set of directions for everything from entering data to processing residuals. If you’ve gotten the complaint from students… Read more »
