Students learn how to calculate speed, density and pressure as compound measures. They apply this knowledge to plot and interpret distance and speed versus time graphs. This topic takes place in Term 4 of Year 10 for Foundation tier and Term 1 Year 10 for Higher. Compound measures follows on from Units of Measure.
know and apply formulae to calculate:
use standard units of measure and related concepts (length, area, volume/capacity, mass, time, money, etc.)
Problem solving lesson on two-way tables and frequency trees.
Three typical exam questions to revise on plotting quadratic, cubic and reciprocal graphs.
Linking cumulative frequency graphs to ratio, percentages and financial mathematics.
