Measuring length
Order three objects by length and compare the lengths of two objects indirectly using a third object
Suggested ages 6–7
Learning journey
Your child is learning practical measurement skills — reading clocks to five-minute intervals, measuring length and capacity using standard units, and working with money including making change.
Evidence of understanding
- Put three ribbons in order from shortest to longest
- Use a piece of string to compare the heights of two objects that cannot be placed side by side
- Explain that if A is longer than B and B is longer than C, then A is longer than C
Assessment prompt
If Measuring length has three pencils of different lengths but can only compare two at a time, can they figure out which is longest — by using a third pencil as a go-between?
