This sounds like a job for Multiplication Boy.
Can Multiplication Boy help Dave with some repeated addition on his number line?
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?

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 number line to jump on in steps of the number they are multiplying.
This clip will be relevant for teaching Maths at KS1 and KS2 in England and Wales, and First and Second Level in Scotland.
