This worksheet teaches students to record the results of repeated chance experiments and use frequencies to compare outcomes and estimate what a spinner or bag contains. The worksheet is split into warm-up questions, standard questions and then extension questions to test you.
The concepts it covers:
- The frequency of an outcome is how many times it happened.
- Results can be written as "out of" fractions: 3 heads in 10 tosses is 3 out of 10, or 3/10.
- Outcomes with a bigger frequency happened more often, so they are probably more likely.
- Results vary each time you do an experiment. More trials usually give a better estimate of the true chance.
What your child will practise:
- Recording results in a tally or frequency table.
- Writing a result as a fraction of the number of trials.
- Comparing outcomes using their frequencies.
- Using results to guess what a spinner, die or bag contains.
- Comparing results with what we expect, explaining any differences.
Every section opens with a worked example, and the download includes a full answer key with step-by-step solutions and teaching notes on the mistakes students most commonly make.
