Rockets and Rekenreks

Ten launches her Rocket Rides into space, using a Rekenrek, an object with five red beads and five white beads. The Rekenrek helps calculate how many beads are needed per rocket ride, and translates that value into pennies, including helping to calculate change. The Decablobs from Planet Ten arrive, but Ten needs a bigger Rekenrek to work out the cost of their journey. Using a bigger Rekenrek, they work out a bigger value of beads and calculate that into pennies, launching another great rocket ride for the Decablobs.
