For parents: how to use this lesson

You don't need to know this topic yourself. The lesson explains each step on screen, one tidy step at a time. Every answer is marked straight away with a worked explanation, so you never have to mark anything.

  1. Read what your child will learn and the big ideas together.
  2. Press Start the lesson below and sit with your child for the teaching and the worked examples (about 19 minutes).
  3. Let them do the practice on their own. They choose Getting started, On track or Challenge – start on On track and move up after a few right in a row.
  4. Finish with the exit ticket and the talk question: “How many different nets of a cube can you find?”
  5. Later that day or the next day: the homework (20 minutes), then a practice test.

Watch out for

  • Counting the same edge twice. Mark each edge as you count it.
  • Thinking any six squares make a cube net. Imagine folding it: do two squares overlap?

Tip for home: Unfold boxes from the recycling to see their nets.

What your child will learn

We are learning to describe 3-D shapes by their faces, edges and vertices and recognise their nets.

Success looks like

  • I can name 3-D shapes.
  • I can count faces, edges and vertices.
  • I can recognise nets.

Key words

face
a flat surface
edge
where two faces meet
vertex
a corner (vertices)
net
a flat pattern that folds into a solid

What to have ready

  • Paper and a pencil
  • This page on a computer, tablet or phone
  • For the hands-on part: Unfold a cereal box to see its net, then fold it back up. Count the faces, edges and vertices.

The big ideas (for the adult)

A 3-D shape has faces (flat surfaces), edges (where faces meet) and vertices (corners).

Prisms have the same shape all the way through; pyramids come to a point.

A net is a flat shape that folds up to make a 3-D shape.
