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, 2/3 of a square, 4 half squares and 1/3 of a square. So the area is 10 + 2/3 + 4 + 1/3 = 15 squares. | This circle has 12 full squares, 4 nearly full squares, 4 nearly empty squares, 6 half squares. The area is difficult to estimate but it is around 19 squares. |
