The Probability Scale
Understand probability as a measure on a scale from 0 (impossible) to 1 (certain); use the language of probability including likely, unlikely, certain, and impossible
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
Can your child explain that probability goes from 0 (impossible) to 1 (certain), place events on that scale as numbers, and tell you whether a game is fair or not?
