What the work shows

The task

The students are:

  • shown a selection of shapes, including squares, rectangles, diamonds, regular hexagons, regular octagons, circles, and equilateral, right-angled, and scalene triangles
  • asked to identify which shapes will tessellate and say why.
Images of student problem solving process

Jonathan's work shows that he knows that four right angles fit around a point, and that he is able to:

  • use the correct convention to show which angles are right angles
  • use knowledge of right angles to show that right-angled triangles tessellate.

Images of student problem solving process

Wiremu's work shows that he knows that four right angles fit around a point, and that he is able to:

  • use the correct convention to show which angles are right angles.
  • use knowledge of right angles to show that squares tessellate.
