SkillrHub Practice guide

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

Worked model: Model data: the same toy car travelled 61, 60 and 62 cm on smooth card, and 28, 30 and 29 cm on felt. What pattern is shown?

Worked answer: The car travelled farther on smooth card in all three trials. Each smooth-card distance exceeds each felt distance. This repeated pattern supports a comparison for these test conditions.

Check your reasoning: Use relevant observations and keep the claim within the evidence.
