Show a seven-year-old the pair 12 and 21 and they may call them the same number, since both use a 1 and a 2. That small confusion is exactly what this 2nd grade comparing numbers to 100 worksheet brings into the open. Sixteen pairs, labeled a to p, sit in two columns on a purple grid, with a pink whale splashing on the side. Between each pair is an empty box, and your child writes or = inside it. Some pairs are far apart, like 99 and 3; others are close, like 97 and 87, and several are exactly equal. A second page gives the answer key.
