Know and use the relationship between familiar units of length, mass and capacity

Examples of what pupils should know and be able to do

Probing questions

  • Ask pupils to sort a set of cards with different measurements (including units) into sets for measuring mass, length and capacity. Which did you find easy? Which are you not sure about?
  • Ask pupils to select one set and sort them in order from smallest to largest. How did you order the cards? Were any hard to order? Why?
  • Can you write 2 km, 4 m or 5 cm in another way?
  • Which would you rather have, 12 litre or 625 ml of orange juice? Why?

What if pupils find this a barrier?
