How to play
How to play
A two-player game where students take turns to run and collect bean bags from a hoop. Using their number sense, they create equations (number sentences) where the closest to a total of 100 wins.
Students take turns to run and collect a bean bag from the hoop.
After each collection, each student decides which of their cells to put that number in.
Students take it in turns to run, choose and place in the grid until all the cells are full.
Students choose an efficient strategy to solve the sum they created.
Whoever has the sum closer to 100 wins and earns a point.
The first player with 10 points is the overall winner.
