GM4-1: Use appropriate scales, devices, and metric units for length, area, volume and capacity, weight (mass), temperature, angle, and time.
Elaboration on this Achievement Objective
This means students will work with the commonly used units of the metric system and measurement devices for:
- Length- kilometre, metre, centimetre, millimetre, using rulers and tape measures
- Area- square kilometre, hectare, square metre, square centimetre
- Volume/Capacity- Cubic kilometre, cubic metre, litre (cubic decimetre), cubic centimetre using jugs, measurement cylinders
- Weight- tonne, kilogram, gram, using scales
- Temperature- degrees Celsius using thermometers
They should also be able to work with standard units for angle and time, degrees, hours, minutes, seconds. In carrying out measurement tasks students should be able to estimate approximate measurements, use units and devices that are appropriate to the task, for example measuring a cup of water in cubic centimetres, read scales with accuracy, for example a ruler to the nearest millimetre or a protractor to the nearest degree, and use symbols to record their results, for example 45mg (45 milligrams) or 6km 2 (6 square kilometres).
Teaching resources for this Achievement Objective
This unit supports students to understand angles as a turn relationship between two rays, and apply their understanding to use angle in sport and design settings.
Identify angles in the environment. Measure an angle using a protractor. Use angles to travel at a bearing. Anticipate the path of a ball as it bounces off a wall. Use rotational symmetry to create a logo.
