GM3-5: Use a co-ordinate system or the language of direction and distance to specify locations and describe paths.
This means students will use co-ordinate systems that are used on maps to specify location and direction (for example Greensborough Reserve is at D1, Ruakura Road runs West-East). The scale of a map indicates distance.
At Level Three students should be able to:
- Give the location of something using co-ordinate references, for example A3.
- Find the location of something given a co-ordinate reference, for example Find Daphne Street at E8.
- Use features of a map to describe movement that would get someone from one location to another, including distance and direction. This includes turns (right, left relative to orientation), main compass directions (N,W,S,E) and approximate distances in metres or kilometres.
- Follow a set of directions given in terms of turns and distances (as above) and show that path they walked on a map of the area.
follow instructions using compass directions
follow instructions on a seating plan
interpret simple co-ordinate maps

- Interpreting simple scale maps.
use scale maps to measure distances
Students will:
- identify the relationship between the relative positions of weights, the centre of gravity of the system, and stability.
Students should discover that:
- the turning force (moment around the fulcrum) produced by gravity is a function of weight x horizontal distance from the fulcrum.
- as the300
- Draw and interpret simple scale maps.
- Use maps or plans to propose actions.
- Understand the use of a compass to specify and find directions.

Students will:
- measure mass, angle, time, and pressure
- record data in tables
- find the function relationships between pressure, mass, distance, time, and angle for a rocket balloon.
Students should discover that:
- force is proportional to mass (you need a bigger force to push a bigger mass the same300
use co-ordinates to describe locations on a grid
Students will:
- use the language of geometry to describe position, direction, and angle
- relate angle of lean to radius.
Students should discover that:
- turning circle is proportional to angle of lean
- cone spacing is proportional to turning circle.
- Describe two dimensional shapes.
- Describe a pathway.
- Create a programme in Scratch for a Sprite to walk out a shape or figure, including:
- Correct numbers of steps
- Correct angles
- Use of repetition
- Use of blocks
- Use of variables and operators
- Read a programme in Scratch and work out the path that the Sprite will take
- Find and describe the location of an object using coordinates and grid references.
- Follow and give directions involving turns (left and right), compass directions (N, S, E, W).
- Follow and give instructions involving distances by interpreting simple scales
- Follow instructions using grid and compass references on a map.
- Devise and use problem solving strategies to explore situations mathematically (guess and check, make a drawing, use equipment).
