A big emphasis for me as an educator is developing learners’ confidence in making decisions, which in part means improving students’ procedural fluency in math. I used to think “well I told them the difference between solving with and without logs, so they know which is which”, but eventually I learned I needed to FORCE …
In 2013 my district adopted new curriculum that was very closely aligned to the (then) new Common Core State Standards. I read these words as a standard I needed to teach: Buy the lesson comparing linear and exponential functions! The textbook we had adopted used the example of simple and compound interest. We’ve all seen …
One strategy that I often use is to have students gather data and then find a regression equation. I’ve done this with both linear and radical functions. Next up: exponential functions in this exponential decay activity. In order for students to really understand what the a-value and b-value represent in the equation y=ab^x, I give …
