This is a set of six "solve the room" cards (including a recording page) and ten practice pages designed to review and reinforce adding two-digit numbers without regrouping.
Each practice page has one problem and uses the UPS (Understand, Plan, Solve) system for solving the problem. (The preview file will show this.) At the beginning, students need more time to figure out the best way to solve the problem.
All pages are in black and white. No answer key is included, but can be made available upon request.
