Ideally print on cardstock. Cut on dashed lines (this is something the child could do as well). You’ll need a dice - perhaps borrow from a board game. Each player takes turn rolling the dice. Each dot represents a unit (single bead). When you collect 10 units, you exchange for a 10 bar. When you get 10 ten bars, exchange for a 100 square. Winner is whoever gets 10 one hundred squares to exchange for a 1000 cube first!
