From Right Brain Math:
Kids love puzzles and patterns. This amazing Tic-Tac-Toe Square for the Threes from Misternumbers (375,000 video views) is a delight to kids when they can play on the Square with 2 simple patterns. They step back with a WOW! To realize that they just made the times tables for the 3s. AND they can re-create the Threes on paper to use the patterns to memorize the times tables or to impress other kids, their parents, their teachers or just for the fun of it. Cool! Kids will thank you for this friendly learning tool and the price is perfect:FREE. It is like 3-D glasses for kids as they look at the two simple patterns of 1-2-3-4-5-6-7-8-9-0 and 000-111-222-3 in the square and suddenly they see they have created the Threes Times Table with a few touches of the keypad. The full app adds 2 squares to both the 3s and 7s and reveals the 6s and 9s. Learning math can be fun for kids and adults!
