Outcomes
MA2-GM-01 uses grid maps and directional language to locate positions and follow routesMA2-GM-02 measures and estimates lengths in metres, centimetres and millimetresMA2-GM-03 identifies angles and classifies them by comparing to a right angleContent dot points
Each dot point has its own page with resources matched to it.
Position: Interpret movement on a map
- Orient a map to determine directions to travel
- Use given directions to follow routes on land and Aboriginal maps without a grid reference system (Reasons about spatial structure)
- Describe a route taken on a map using landmarks and directional language
Position: Locate positions on grid maps
- Locate positions by coordinating horizontal and vertical references
- Use the array (row and column) structure of grid maps to locate position, horizontal before vertical
Length: Measure and compare objects using metres, centimetres and millimetres
- Measure and record lengths and distances using a combination of metres and centimetres
- Estimate lengths and distances using known lengths as benchmarks, in metres and centimetres and check by measuring
- Compare and order lengths and distances using metres and centimetres
- Recognise the need for a formal unit smaller than the centimetre to measure length
- Identify that there are 10 millimetres in one centimetre
- Use the millimetre as a unit to measure lengths with a ruler
- Record lengths using the abbreviation for millimetres (mm)
Angles: Identify angles as measures of turn
- Identify angles with 2 arms in practical situations
- Identify the arms and vertex of an angle
- Recognise an angle as the amount of turning between 2 arms
- Compare angles and explain that the length of the arms does not affect the size of the angle (Reasons about spatial relations)
- Use the term right angle to describe a quarter-turn in a range of orientations (Reasons about spatial orientation)
