Elaboration on this Achievement Objective

This means students will apply their understanding of the measurement system, particularly of length and angle. This involves converting the scale on a map to actual measurements and describing direction given the orientation of North.

  1. Give or interpret the location of a feature on a map using grid references, distances and direction from a landmark, for example AA 24 (Street map), 536 721 (topographical map), 160m South-East of the library, Latitude 12o South, 77o East (World map), 2047km South-West of Los Angeles.
  2. Follow instructions given by others using compass directions, distances and grid references by interpreting a scale map, for example travel from New Plymouth to Tauranga.

Irrigating the trees

Level Four
Geometry and Measurement
Units of Work
This unit examines the use of rotation to specify angles as an amount of turn. The context of the unit, irrigating trees, requires the calculation of lengths and measurement of angles based on a four-quadrant number plane.
  • Identify the location of a point on a four-quadrant number plane using coordinates.
  • Average the x and y values of a set of coordinates to locate the centroid of the points.
  • Use scale or Pythagoras’ Theorem to find the distance between points on a number plane.
  • Measure the bearing (angle300

Units of Work
In the film The Hunt For Red October, at one point the escaping Russian submarine has to navigate a complicated underwater trench. This unit is built around that idea and brings in the measurement of angle and distance. It is expected at this stage that the students will know how to use protractors.
  • Follow directions given in bearings.
  • Invent their own maps using bearings.
  • Use a protractor to produce maps.
