SkillrHub Practice guide

Each attempt draws five questions from the full bank. Repeat an attempt to meet more questions.

Worked model: Two labelled coins A and B are tossed. Which is a complete outcome list?
  • Worked answer: HH, HT, TH, TT. HT and TH are different when the coins are labelled.
  • Check your reasoning: Count the relevant recorded outcomes, including both orders when grouping mixed coins.
  • Materials and practical tasks: Have a coin, counters or spinner and a recording sheet ready. Record every outcome honestly, repeat the experiment and compare same-sized groups of trials.
  • Written responses: An adult checks your completed work against the task-specific guidance before awarding credit.
