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.
Numbers go up to 20, but no problem bridges ten. Additions like 12 + 5, 14 + 3 or 11 + 6 keep the ones under 10, and subtractions like 17 − 4 or 19 − 6 never need to break into the ten. Answers that land exactly on a ten are allowed, so 7 + 3 = 10 and 13 + 7 = 20 appear, while 8 + 5 or 13 − 5 do not. The idea to take away is that 15 + 3 works just like 5 + 3 with a ten in front.
