What a fun and engaging way for the students to think about all of the facts that make 20. This sheet has mostly number sentences that equal 20, with a few distractors that they will X out. Most of the facts are up to 20, addition and subtraction, with a few more challenging number sentences at the end. There are repeats as well to help promote automacity in recalling facts. Fun, cute, engaging and I am soon creating a center in which the kids sort the facts that make 20 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! Also check out my Ways to Make 10, 12, 15, 18, and 25! Let me know if I can create any others for you! Thanks!
