A turtle seen from the side, with a patterned green shell, a little head and stubby legs. The rounded shell appears first, and the head with its eye gives the picture away at the end.
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.
