Lesson details
Key learning points
- When you estimate length, you think carefully and make a sensible guess.
- When you find a measurement, you use a ruler so it is more accurate.
- Estimates and measurements can be recorded in a table.
- Information in a table can be used to describe and compare lengths.
Common misconception
Children may try to estimate length without aligning their object with the start of the known length (such as a 10 cm strip of paper).
Each time you make an estimate, model aligning the object you are measuring with the start of the strip of paper. Make links to when we measure with a ruler, knowing we always have to line up the object we are measuring with 0 cm.
