Explicit teaching — I Do (~15 min)

1. Transformations WA6MMGTW1

Demonstrate slide (translation), flip (reflection) and turn (rotation) with a cut-out shape on the visualiser.

2. Unit conversion WA6MMGTW2

Show 1 m = 100 cm, 1 km = 1000 m using the decimal/place-value link; extend to g ↔ kg and mL ↔ L.

3. Area of rectangles WA6MMGTW3

Build the rule by covering a rectangle with unit squares → length × width; record the steps.

4. Angles WA6MMGTW4

5. Cartesian plane WA6MMGTW5

A Cartesian plane with x and y axes crossing at the origin, four labelled quadrants, and four example points with coordinates.
Two number lines crossing at zero create four quadrants.

Plot points in all four quadrants and read coordinates as (x, y) — across first, then up or down.

Guided practice — We Do (~20 min)

  1. Transform it. The class transforms a shape on a grid — translate 3 right and 2 down, reflect over a line, rotate a quarter-turn — and describes each.
  2. Convert together. Work a set of length/mass/capacity conversions, verbalising the ×/÷ by 10, 100 or 1000.
  3. Area. Find the area of several rectangles, then tackle a "find the missing side given the area" problem.
  4. Angles. Find unknown angles using right-angle, straight-line and vertically-opposite relationships.
  5. Plot. Plot a set of coordinates that join to make a shape across all four quadrants.

Independent practice — You Do (~15 min)

Worksheet (sections map to WA6MMGTW1–TW5):

  • describe and perform translations, reflections and rotations on a grid;
  • convert between metric units of length, mass and capacity;
  • calculate the area of rectangles (including a missing-side problem);
  • find unknown angles and explain the reasoning;
  • plot and name points in all four quadrants.
