For most students (and adults!) using numbers rather than words to convey likelihoods, probabilities, or degrees of confidence is not intuitive. To bring more numeracy and probabilistic thinking to classroom conversations, it is helpful for students to shine a spotlight on the numerical values that may already feel intuitive to them. This short activity guides students into discovering and naming those familiar probabilistic values so that they can begin referencing them more regularly.

Students use a number line to capture the probabilities that feel most natural to use in everyday communications.
