The range of temperature is the difference between the high temperature and the low temperature. We can complete the chart to determine the largest range.

| Day | Temperature Range $\left({ }^{\circ} \mathrm{C}\right)$ |
| :--- | :---: |
| Monday | $5-(-3)=8$ |
| Tuesday | $0-(-10)=10$ |
| Wednesday | $-2-(-11)=9$ |
| Thursday | $-8-(-13)=5$ |
