Measuring temperature
Mathematics · Number Representation & Place Value · procedural
Use negative numbers in context (temperature, finance, sea level); calculate intervals across zero
What mastery looks 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
Check your understanding
If a bank account goes from −£45 to +£120, can Measuring temperature work out the total change — counting through zero to get £165?
