Securing understanding of ordering and comparing numbers
I can confidently order and compare a variety of numbers and measures.
Lesson details
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.
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.
Keywords
Inequality - An inequality is used to show that one number or measurement is not equal to another.
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.
