Then we made collages using the marked-up photos in Pic Collage. They turned out pretty good if you ask me.:)
As with most math concepts I teach, I put a couple of QR code scavenger hunts up around the room for the kids to complete during centers. This one has them identifying various polygons.
And this one, which is a FREEBIE in my store, has them identifying types of lines and angles. The QR code on each phone leads them to the next term until the hunt is completed.
Maybe some of these ideas can help get you through test prep season.;)
