A cheerful green frog with bulging eyes, a wide smile and a light green belly. The two eyes on top of the head make it easy to recognize once they are colored.
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.
