SUM-IT is a game for students that focuses on Addition. A fun way to not only practice addition skills, but the skills of looking ahead and trying to think how they might reach the SUM-IT before their opponent does. Students are given a Sum-it number at the summit of the mountain, and a starting number at the bottom of the mountain. Students will take turns calculating and then passing off to their opponent. Using certain rules (Like adding One or Three at a time only, and some levels where double digit adding is required), students must add their way to the sum-it before their partners do. There are 35 different sum-it game levels to try and conquer.
