After searching everywhere for something to use with my recursive formula and explicit formula lessons, I finally just made one that was exactly what I wanted. This foldable has notes on the front for students to look back to for review and help, and plenty of practice problems on the inside. I use interactive math journals, and these fit right into their journals as they are folded in half on the short edge. You'll want to set your printer setting to print double sided on the short edge, not the long edge, so that the paper will fold right side up on both sides. :)
My Algebra 1 students love these practice foldables. See the rest of my store for the matching "Explicit Formulas Foldable" made in the same format.
