Learning Wrap-ups are even better than before. They now feature a new "Key" shape and stay together with a rivet at the top. There is a single string that's already attached, making them easier to use and organize. They still 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, and then turn the Wrap-us over to see if they got it right. They utilize many learning senses and are fun enough that students are willing to use them over and over until they master their facts. Each set covers 120 basic facts. Use a stopwatch to measure improvement and to see how fast they can really go. Choose from many combinations of individual titles to kits that provide value and savings. Each set contains 10 self-correcting keys and covers all the facts for that operation.
