“Smart Crossing the River” is a way to help children learn mathematics and build knowledge by playing with balloons.
It is known that a balloon can carry 2LB items. There are two ways to play the game. The "balloon load" calculates how many balloons need to carry the goods across the river according to the weight of the household items. “Building a bridge” is based on the weight of the building tools to calculate how many items need to cross the river. If you correct the 10 questions, you can build the bridge successfully.
