When you are out and about, point out measurements of length or height in the real world – like width restrictions when driving or height restrictions for fairground rides.
To help your child compare different lengths and heights, you could ask them to choose five objects from around your home and measure their length using a ruler. Ensure that your child uses their ruler correctly, beginning at the zero and measuring the lines accurately. Then, ask them to order the objects from longest to shortest. Can they write three sentences to describe the objects using the words longer, longest, shorter, and shortest?
