Lower Key Stage 2
Meaning
Area is the size of a surface.
About Area
- If a rectilinear shape is drawn on a grid the area can be found by counting the number of squares inside the shape.
 |
 |
 |
| The shape has 20 squares inside it, so the area is 20 squares. | This shape has an area of 14 squares. | This shape has an area of 15 squares. |
Upper Key Stage 2
Meaning
Area is the size of a surface.
About Area
- If a rectilinear shape is drawn on a grid the area can be found by counting the number of squares inside the shape.
|
|
|
| The shape has 20 squares inside it, so the area is 20 squares. | This shape has an area of 14 squares. | This shape has an area of 15 squares. |
- If an unusual shape is drawn on a grid the area can be estimated. The answer will not be exactly correct, but it will be close.
 |
 |
 |
| This shape has 12 full squares and 3 half squares. So the area is 12 + 3.5 = 15.5 squares. | This shape has 10 full squares, 6 half squares and two other . | This shape has an area of 15 squares. |
