A little bat with pointy ears, yellow eyes and wide purple wings. The spread wings fill the grid from side to side, so children can watch the shape grow outward as they solve.
Problems use two-digit numbers up to 100, mixing those with and without regrouping: 36 + 27, 45 + 30, 82 − 49, 70 − 26. Children practice adding tens and ones separately, trading ten ones for a ten, and subtracting when the ones digit on top is too small, as in 82 − 49. Mental strategies such as adding 30 and then 6 work well here, and so do column methods on scrap paper.
