Ordering negative integers
I can compare negative integers using < and >.
Lesson details
Key learning points
- Negative integers in context can be ordered.
- Negative integers can be represented and compared on a number line.
- Negative integer comparisons can be made using the symbols < and >.
Common misconception
That just the absolute value is considered and not the integer in its entirety.
Encourage pupils to consider the integers as temperatures even if there are no temperature units.
Keywords
Absolute value - The absolute value of a number is its distance from zero.
When doing the 'cool cash' part of the lesson, invite pupils to come up to the board and add further examples to the 'winning' and 'losing' temperatures. This could lead to further discussion about which temperatures are realistic.
