Lesson details
Key learning points
- Rulers are marked in centimetres
- Counting in ones helps you to measure in centimetres
- Counting in tens helps you to measure in metres
Keywords
Ruler - A tool for measuring length.
Metre stick - A tool for measuring length which is one metre long.
Common misconception
Children may align the end of their object with the end of the ruler, rather than zero.
Use a sticker or coloured pen to highlight the zero on the ruler so that children's attention is drawn to the zero when they are measuring length using a ruler.
The examples within this lesson refer only to full metre lengths and children are not expected to work with mixed units at this point. They do not need to be aware of the conversion between metres and centimetres, but should know that a metre is bigger than a centimetre.
