**Scheme of work: GCSE Foundation: Year 10: Term 4: Compound Measures **

- know and apply formulae to calculate:
- rectangles
- rectilinear composite shapes
- area of triangles
- volume of cuboids
- use standard units of measure and related concepts (length, area, volume/capacity, mass, time, money, etc.)

- use standard units of mass, length, time, money and other measures (including standard compound measures) using decimal quantities where appropriate
- round numbers and measures to an appropriate degree of accuracy (e.g. to a specified number of decimal places or significant figures)
- change freely between related standard units (e.g. time, length, area, volume/capacity, mass) and compound units (e.g. speed, rates of pay, prices, density, pressure) in numerical and algebraic contexts
- use compound units such as speed, rates of pay, unit pricing, density and pressure

- It is useful to calculate compound measures through the unitary method where ratios are in form 1 : n.
- Distance â€“ Time graphs can be extended to Speed-Time/Acceleration-Time graphs.
- Use algebraic techniques to manipulate the various formulae so that other measures can also be found.

- Density, pressure and time do not have to have fixed units. For instance, a speed can be m/s or mph; density can be g/cm3 or kg/3.
- Students often have difficulty remembering which measure to divide by. The speed, pressure and density triangles are helpful to recall the relationship between the various measures.
