What a fun and engaging way for the students to think about all of the facts that make 15. This sheet has mostly number sentences that equal 15, with a few distractors that they will X out. Most of the facts are up to around 25, addition and subtraction, with a few more challenging number sentences at the end. There are repeats as well to help promote automaticy in recalling facts. Fun, cute, engaging and I am soon creating a center in which the kids sort the facts that make 15 into true/false. This would be a great follow-up to the center, or it can be done alone. Learning basic facts is a crucial building block for other 2nd grade math skills, and especially for multiplication in 3rd grade. The more practice, the better!
