Great number sense activity! I used this with my students as a warm-up during my addition and subtraction of larger numbers unit. Students color all of the ways to make 50. This is great to do after brainstorming a web on the board of all the ways to make 50 (or any number). They can apply what they've practiced in class with this independent assignment or math center. Check out my Ways to Make Centers and Worksheets (like this one) for 10, 12, 15, 18, 20, 25, 30, 40 and 100! Enjoy!
