I created flashcards to use with the Common Core Standard - Adding Within 5 for Kindergarten. I cut scrapbook paper to 8 1/2 x 11 and put it in the printer so I print on the blank side. When my cards print, I laminate and cut them out. I can put them under the document camera during snack and the kids can solve the problem. I also throw them in a tub with counters for the kids at centers.
