Addition and Subtraction Puzzles

Addition and subtraction are two of the four fundamental operations of arithmetic. These fun and engaging puzzles are an exciting way for your child to self-grade their own arithmetic. There are eleven puzzles. Each puzzle features both addition and subtraction of 2, 3, 4, 5, 6, 7, 8, 9, 10, 100, or 1000. Each puzzle consists of two pages (front and back). The first page has a scrambled 20-piece puzzle on the front and numbers with alignment arrows on the back. The second page contains a puzzle template with 20 arithmetic problems and alignment arrows.
