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.)
How to introduce the sin, cos and tan trigonometric identities.
How to teach calculating the original amount after a percentage change.
The importance of the range when comparing comparing datasets.
