How can you tell they’ve got it: Measuring temperature?

If they’ve got it, you’ll see things like: The temperature falls from 3°C to −5°C — what is the drop? (8 degrees); Calculate the difference between a bank balance of −£120 and £350; Order −7, −3, 0, 2, 5 on a number line and find the interval from −7 to 5. Or just try it together: If a bank account goes from −£45 to +£120, can your child work out the total change — counting through zero to get £165?

Measuring temperature

Your child can count across zero with negative numbers. If a bank balance goes from −$45 to $120, they find the change is $165.

In curriculum terms

Use negative numbers in context (temperature, finance, sea level); calculate intervals across zero
