You’ve heard of mental math. How about physical math to wake up those kids? Throwing manipulatives into any learning process allows the brain to acquire knowledge in a new way. Besides, it’s fun! “Sign Wars” represents one activity from my “Let’s Get Physical Math” unit also available on this site.
This activity is designed to reinforce new or old skills in critical thinking, problem-solving, computation, and concepts. It can be used as enrichment or part of the warm-up process on “regular” math days, and it can be fueled by concepts and existing math problem available in your textbook.
Student pairs are given small hand-made or purchased tiles with plus signs and minus signs on them. They will discover the rules for adding signed numbers.
