It is a way to practice and build number sense using basic addition and subtraction facts with you students. I’ve used this with my 1st graders, but I would recommend it for kindergarten through 3rd grade to build and reinforce number sense in the younger elementary school age.
This activity is great to use on an interactive board, my students enjoyed taking turns and coming to the board and filling in problems and 10 frames. It can also be used as a reusable worksheet that you laminate or put in a page protector or as a handout worksheet to have students complete on their own, as a class, or for a math center.
