Hop the frog across the river one numbered turtle per lane — each +2 or −1 moves it along the number line, and it gets home only if the hops land exactly on 10.
Ten Frog plays like Frogger: the child picks one numbered turtle in each river lane and every hop (+3, +1, later −2) moves the frog along a number line of lily pads, so crossing the river means composing hops that land exactly on 10 — first counting up, then counting back, then mixing both while turtles dive under. A wrong crossing splashes back to the start with the child's own sum ("7 + 2 + 3 = 12, not 10"), which targets miscounting the gap to 10 and counting the starting number as a hop, and no crossing ever ends the game. Best for Grades 1–2.
