Learning intention
Students will learn how to:
compare and order lengths using direct comparison.
Success criteria
I will know I have been successful if I can:
- order lengths from longest to shortest.
Prerequisites
None
Languages
Reinforce the use of language related to measurement: long, longer than, longest, short, shorter than, shortest
Misconceptions
- Lengths that ‘stick out’ further (regardless of whether the ends are aligned or not) are longer.
Before the video
- ‘What is length?’ Discuss.
- Ask the students to find 1 long object and 1 short object. Ask the students to compare their objects with a partner. Which object is the longest/shortest? How do you know?
During the video
First viewing:
Watch the video without stopping or pausing. Then, ask the children to explain what happened in the video. Begin to draw out key vocabulary or possible misconceptions.

Finding the longest length |
How could Ed work out which is the longest strip? |

Lining up end-to-end to measure |
Why has Ed put them side-by-side when he is not sure? |

Using key vocabulary |
What did Ed need to do to make a pyramid? Recap the steps together. |
After the video
Make a pyramid:
- Students follow Ed’s steps to make their own pyramid using the printable (do not glue the strips down yet).
- Ask the students to mark bricks on their pyramid using the top brick and state the measured length (in bricks) of each layer of the pyramid. (Recap from 3:22 on video if necessary.)
- Pair work: ‘Swap 2 layers of your pyramid. Ask your partner to work out which 2 layers have been swapped.’
