I hope you find this product to be useful in your classroom center rotation. I created this product to help my students grasp and continue practicing fact families. My students were having a great deal of trouble with subtraction until I introduced this activity. I used this along with some sort of manipulative to help them reach the correct answers.
This product contains enough color-coded pieces for five students per center- simply print, cut, laminate, and watch your students enjoy learning their math facts!
