Lengths
Lengths helps children practise measuring and comparing lengths in centimetres and metres, and solving short length word problems. Read the short guide and look through the examples before choosing online practice or a printable worksheet.
How to solve this
- Length is measured with a ruler; the main units are centimetres (cm) and metres (m), with 100 cm in 1 m.
- Always align the zero mark of the ruler with the start of the object before reading the length.
- Check by estimating first: a fingernail is about 1 cm, a door is about 2 m — does your answer fit?
Examples
35 cm + 20 cm = ?
55 cm
1 m = ?
100 cm
