I use these with my students for the beginning of class to practice counting, number identification and writing! Print out the 4 pages, laminate them, and attach to a manila folder (one page per side). Students can count the dollar bills and write the answer in a dry erase marker!
I have also included a numbers page of answers. For my lower level students, I laminate, cut, and velcro 4 numbers at the bottom of each page. Students can then count and match the number.
