Chapter summary
| Skill | Method |
|---|---|
| Changing units | Going to a smaller unit: multiply. Going to a bigger unit: divide. Move the decimal point one place for each power of ten. |
| Time | 1 hour = 60 minutes. Hours to minutes: multiply by 60. Minutes to hours: divide by 60. Put the part of an hour after the point. |
| Miles and kilometres | 1 mile is about 1.6 km. Miles to kilometres: multiply by 1.6. Kilometres to miles: divide by 1.6. |
| Parallelogram | Area = base × perpendicular height. Do not use the slanted side. |
| Triangle | Area = (base × perpendicular height) ÷ 2. |
| Perimeter and area | Shapes with the same area can have different perimeters. Cutting a corner out keeps the perimeter the same. |
| Volume | Cuboid: length × width × height. Cube: side × side × side. 1 m³ = 1 000 000 cm³. |
Can you…?
- I can change between metric units, including decimals up to three places.
- I can convert between hours, minutes and seconds, including decimal hours.
- I can convert between miles and kilometres, using 1 mile is about 1.6 km.
- I can find the area of a parallelogram and a triangle, using the perpendicular height.
- I can explain why shapes with the same area can have different perimeters.
- I can say when a formula can be used for the area or volume of a shape.
- I can find the volume of a cube or cuboid, and convert cubic units.

- Area
- The amount of space inside a flat shape, in square units.
- Volume
- The amount of space inside a solid, in cubic units.
