Adaptive teaching
Pupils needing extra support:
Could measure five balloons and not include the repeat data results; could use the Knowledge organiser to research the answers to the Recap and recall retrieval race.
Pupils working at greater depth:
Should calculate the average balloon circumference, using the repeat data; could be encouraged to consider and discuss why gathering repeat data is important (it improves the reliability of results and allows anomalies to be identified); could choose an extension activity relating to reversible and irreversible changes from the Resource: Stretch and challenge: Properties and changes.
