What a learner can do afterwards

  • Join two triangles to make a rectangle or larger triangle
  • Use pattern blocks to fill a hexagon outline
  • Create a picture or design by combining basic shapes

The lesson

You know shapes like triangles and squares. Put two shapes side by side. They can make one whole new shape.

Two triangles together make this rectangle.
Try it together

Ben places six triangle blocks together. They fit with no gaps and make a hexagon.

Good to know

Try turning a shape around. Sometimes a turned shape fits together better.

Small shapes can join together to make bigger, new shapes.
