Climb the wall by solving math! Each hold shows a problem like 7 + 5 and three stones. Reach to the stone with the right answer and close your fist to grab it — then pull your hand down to haul yourself up to the next holds.
Stand back so the camera sees your head and both hands. Reach a hand onto a stone, then squeeze it into a fist to grab.
Pick at least one kind of math to play.
