Here students are given nine different scenarios/events, such as “You will spin a 10 or less than 10 on a fair spinner with 10 sections numbered 1 - 10.” alongside a six-interval scale with “impossible” at one end and “certain” at the other.
Learners must place an arrow on the scale next to each event to show the chance of the event happening. Learners are also asked to write this probability as a fraction.
All probabilities can be shown on an interval marker on the scales, although some fractions, such as 4⁄8, will need to be simplified before doing so.
