What a learner can do afterwards

  • Stand two children back-to-back and say who is taller/shorter
  • Directly compare the heights of two towers and describe one as taller
  • Use 'longer' and 'shorter' to compare two ribbons placed side by side

The lesson

Put two things side by side to compare. One can be longer or shorter. The other can be taller or shorter too.

<
Tower B has more blocks. Tower B is taller than Tower A.
Try it together

Maya and Sam stand back-to-back. Maya's head is higher. Maya is taller than Sam. Sam is shorter than Maya.

Good to know

To compare fairly, line up one end of each thing. Then look at the other end.

Line things up, then look which end is longer or taller.
