Explain how to calculate the area of a rectangle using multiplication

Maths

Measure the area of flat shapes using square centimetres

Measure the area of flat shapes using square metres

Calculate the areas of rectangles using multiplication

Calculate the area of shapes made from 2 rectangles by decomposing the shape in different ways

Calculate the area of compound rectilinear shapes

Choose an efficient way to decompose a compound shape to calculate the area

Calculate missing dimensions in rectangles and compound rectilinear shapes

Calculate the area of shapes made from 2 or more rectangles

Use knowledge of area to solve problems in a range of contexts

In this unit pupils will calculate the area of a rectangle using multiplication and use their knowledge of area to solve problems. In the future unit pupils will explain what volume is using a range of contexts and describe the units used to measure volume. They will explain how to calculate the volume of a cuboid.

In the prior unit pupils explained area and measured using counting as a strategy. They made different shapes with the same area and compared the area of different shapes. In this unit pupils will calculate the area of a rectangle using multiplication and use their knowledge of area to solve problems.

Link area of rectangles to multiplication

Which of these rectangles has the dimensions correctly labelled ?

What is the area of this shape? {{ }} cm²

What is the area of the shaded shape? {{ }} cm²

Order the shapes by area, starting with the smallest area.

Which times table fact is being shown here?

False. The shapes meet at the vertices so they are three shapes.

True. There are 3 squares that each have the area of one square metre.

True or false? This shape has an area of three square metres.

Which of these statements are true for a square?

Match each parts of the rectangle to the correct letter.
