How to play

-- Launch the game and display it on your screen --
Explain to your students that the climber on the screen is going to scale a wall, but he can only climb a total of 21 steps before he gets too tired and falls. You can take turns in groups or let individual students go one at a time. Just have the student say, “Climb” and the tech running the game will hit the spacebar. This will cause the climber to take a random number of steps between 1 and 10. If a student gets close to 21, but doesn’t want to risk going over, they can stop and take that score. If a student continues and goes over 21, their climber will fall and they won’t have any points.
The winner is the student/group who can get the closest without going over.
