One of my last Algebra 2 units before state testing was arithmetic and geometric sequences and series. Our students are given the formulas for the nth term and the sum of the first n terms, but they are given no explanation for what each variable represents.
So, I like to spend an entire class period discussing what each variable represents. Then, we look at word problems and label all of the information with the correct variable. The kids hate it, but it really helps them in the long run. This year, I had a handful of students who decided to just tune out this entire explanation. Well, to be honest, they tuned out most of what I said this entire year. And, their test scores certainly reflected that. :(
By now, you know that I love foldables. I adore foldables. I'm pretty sure I think and lesson plan in terms of foldables and graphic organizers. There are some foldables I make that are just meh. Then, there are the foldables that I can't wait to show my kids. The ones I'm about to post belong to the latter category.
I think these are pretty self-explanatory, so I'm going to post the pictures without much commentary. If you have questions about anything, please ask! I've uploaded templates for the formula foldables at the bottom of this post. Enjoy!
