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. Learning Wrap-Ups still offer a fun and unique way to help students learn. 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.
