What your child does, card by card
Game time: Wildwood Number Duel. Tame Leo with mind math! PlayBuddy opens the lesson: “Game time! Let's play with the beads!”
Game time: Wildwood Number Duel fills the lesson window. Leo the lion cub bounds toward PlayBuddy’s camp; 10 mind sums (3 + 8 + 9, 6 + 7 - 4, 9 + 9 + 2, 15 + 23, 8 + 5 + 6 - 3, 42 - 17, 7 + 7 + 7, 28 + 34, 9 - 4 + 8 + 6 and 56 + 25) come one at a time, and each right answer, picked from three chips below, lets PlayBuddy toss an acorn. Enough acorns and Leo is tamed for a hug; nobody loses.
Leo is tamed! Wildwood Number Duel is on the Games page too.
