The measurement of a flat surface. It measures a 2D space.

Explain how to compare the area of different shapes

Maths

In this unit pupils will explain what area is and measure using counting as a strategy. They will make different shapes with the same area and compare the area of different shapes. In the future unit pupils will calculate the area of a rectangle using multiplication and use their knowledge of area to solve problems.

In the prior unit pupils completed and composed symmetrical shapes from two congruent shapes and investigated lines of symmetry in 2D shapes. In this unit pupils will explain what area is and measure using counting as a strategy. They will make different shapes with the same area and compare the area of different shapes.

Understand the concept of area

Select all of the items that would have a greater area than the circular clock face. 

A 2D shapes with straight sides and only right angles.

Match the words with their correct definitions. 

Put the following objects in descending order according to their area. 

The two rectangles have the same area (six square units).

The size of the square units in these shapes is different. 

Select all of the statements that are true. 

Put the following shapes in ascending order according to their area. 

It is impossible to compare the shapes because a is not rectilinear.

The two shapes have exactly the same area. 

Match the symbols with the correct meanings.

Which of the following statements are correct?

Order the following numbers so that they are in ascending order. 

Select all of the sequences that are in descending order. 

The small triangles in each shape each make up half a square unit. 

In both shapes, two small triangles combine to make one square unit. 

This lesson will soon be taken down.
