My students love these number puzzles. They are a great way to practice different strategies for adding and subtracting two-digit and three-digit numbers. They help students play with decomposing numbers to build addition and subtraction math strategies
Created for elementary age students, 2 pages of addition problems set up in a grid with boxes for "regrouping"/"carrying." The grid format helps students keep their columns lined up, and the boxes will aid them in remembering to "carry" or "regroup" tens.
