Area of Rectangles: Rows by Columns

Pupils learn to find a rectangle's area by multiplying rows by columns, connecting this to counting every square and writing the answer in square centimetres.

1 - Getting Started ~4 mins

Illustration for Getting Started Here is a rectangle covered in equal squares. The top row has 5 squares, and there are 4 rows stacked up.

Key point

If each row has 5 squares and there are 4 rows, do we really have to count every single square to find how many there are? Or is there a faster way?

👇 Mark your steps as done as you complete them.

+5 XP

2 - Watch and Notice ~9 mins

Each interactive shows a rectangle made of equal squares and its rows-by-columns multiplication. Count the squares with the class first, then check that rows times squares-per-row lands on the same area.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~9 mins

Key point

Today we work through four rectangles one after another in the same board tool: 3 × 4, then 5 × 4, then 6 × 5, and finally 8 × 6. For each one, the pupil at the board builds the rows and columns and says the multiplication.

Everyone else has a job too: before each rectangle is built, predict the multiplication aloud with the class. Then we check that rows-times-columns matches counting the squares.

Build the rectangle, then multiply

COPYBOOK MOMENT

In your maths copy, draw a 5 cm by 3 cm rectangle on the squared page. Count the squares to find the area, then write the matching multiplication underneath it:

5 × 3 = ___ cm²

5 - Class Challenge ~8 mins

Key point

Today we find the area of these rectangles in turn: 3 × 4, then 6 × 5, then 9 × 4, and finally 7 × 5. Each one is a little bigger, so the times-table fact does more of the work as we go.

Find the area of each rectangle
