Measuring length

Order three objects by length and compare the lengths of two objects indirectly using a third object

How to tell they’ve got it

Tick these off as you see them — no test required.

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

Try this together

If your child 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?
