Securing understanding of ordering and comparing numbers
Lesson details
Learning outcome
I can confidently order and compare a variety of numbers and measures.
Key learning points
- In order to compare measures, conversion may be necessary.
- Measures can be converted using place value.
- Values can be ordered using inequality symbols.
Keywords
Inequality - An inequality is used to show that one number or measurement is not equal to another.
Common misconception
The number with the largest value is the greatest measurement.
Converting to the same unit can be helpful before comparing the place value of the digits. e.g. 0.4 m is bigger than 40 mm.
Teacher tip
Be careful when talking about metric units. For example, cm being 100th of a metre, that pupils don't think that to covert cm to m you divide by 100.
