Learning Wrap-Ups: Subtraction
Learning Wrap-Ups offer a fun and unique way to help students memorize their math facts. Students wrap the string from the problem on the left to the answer on the right, then turn the wrap-up over to see if they got it right. Use a stop watch to measure improvement and to see how fast they can really go. Each set contains 10 self-correcting boards and covers all the facts for that operation.
