Big Ideas Learning offers a way for groups of middle school learners to compete as they take math chapter tests. I’ve used versions of such group testing with my fifth grade students. Worked great. While you’re on their site, check out their free newsletter and posters. They offer 1,600 cartoons! Hmm, and all available with and without a Tablet or other mobile PC.
