Subtraction Wrap-ups, Set of 10 by Learning Wrap-Ups
Each set of Wrap-ups includes 10 different keys and a string that is already attached for wrapping from the problems to the answers. All keys have a self-correcting feature built in on the back. They utilize many leering senses and are fun enough that students are willing to use them over and over until they master their facts. Each set cover 120 basic facts. by Learning Wrap-Ups
