Maths KS1 / KS2: What is multiplication?

Dave is building a new garden wall for Mrs Sharma. It’s taking a very, very long time.

He is doing his best but keeps running out of bricks.

This sounds like a job for Multiplication Boy.

Can Multiplication Boy help Dave with some repeated addition on his numberline?

Will Dave be able to calculate exactly how many bricks to order to get the whole wall finished in one go?

Will Mrs Sharma’s wall ever actually get finished?

This clip is from the series A World Without Maths.

Teacher Notes

Children could explore multiplication problems linked to the story, using objects or pictures to support their understanding.

For example: Dave drinks 5 cups of tea a day, and has 2 sugar cubes in each cup.

How many sugar cubes will Mrs Sharma need to keep Dave going for the day? How many groups of 2 will you need? How might you write out the calculation?

Some children might use a numberline to jump on in steps of the number they are multiplying.
