8 SPRING 2

DEVELOPING NUMBER

OVERVIEW

Note: Multiplying and Dividing with fractions is down to be taught during Year 8 Autumn 1 in the original WRM scheme but this has been moved here to enable more time to focus on ratio and proportionality. Learners have had lots of experience of multiplying and dividing with fractions in Year 6. In this half term we seek to retrieve this knowledge and deepen understanding.

Following this learners with focus on how to increase and decrease an amount using a percentage multiplier. Financial maths is developed through the contexts introduced eg. profit, loss and interest. Percentage multipliers will then also be used to help learners understand how to calculate percentage change and original amounts following a percentage change.

The original WRM scheme also includes additional work with Standard Form. Across our trust this has been taught in Year 7 in line with the WRM HPA strand and to enable our learners to see standard form in both Maths and Science in Year 8. If time allows please also retrieve work with standard form.

Please see here for additional medium term plans and resources including LPA & HPA guidance, further exemplar questions, worksheets and videos.
