Chapter summary
| Skill | Method |
|---|---|
| Choose a unit | Small lengths: cm. Long lengths: m. Light things: g. Heavy things: kg. Small amounts of liquid: ml. Big amounts: l. |
| Units to change | 1 m = 100 cm. 1 kg = 1000 g. 1 litre = 1000 ml. |
| Read a ruler | Put the 0 at the start. Read the number at the other end. Take the start away if it is not 0. |
| Read a scale | Look where the needle points or where the arrow stops. Read the number in kg or g. |
| Read a thermometer | Read the top of the red line in °C. Each small mark is one degree. |
| Read a jug | Read the water line. Each number is 200 ml apart, with marks every 50 ml. |
| Compare and record | Change to the same unit first. Write <, > or = between the amounts. |
