Explore angles as you theoretically shoot pool balls across grid paper in an attempt to land them in the pockets of the pool table. Where will the ball land if the pool table is a different size or the ball travels along another diagonal? (If this activity looks familiar it’s because it was featured on Celebration of Mind’s 2017 postcard!)
