How we teach it

This is what sits under the answer sheets in the app — the same cards, clips and lessons your child sees after a question.

More lessons for this topic are on the way.

One question, as your child sees it

And the answer sheet that follows a second wrong try: what we know, what we need, the steps, a check, the answer.

Ms Thomas is pretending to be a 3D shape. She gives three clues:
• I have three dimensions.
• I have one curved surface.
• I have no flat surfaces.
Which shape is she pretending to be?
  • Aa cylinder
  • Ba sphere
  • Ca cone
  • Da circle

First hint: Go clue by clue. Which shapes have a flat surface anywhere on them? Those are out.

The answer sheet

Take the clues one at a time.

a cylinder has two flat circles, one at each end, so the last clue rules it out.

a cone has one flat circle at its base, so it is out too.

a circle is flat: it is a 2D shape, and the first clue asks for three dimensions.

that leaves the sphere. A ball is curved all the way round with no flat part anywhere.
