Numbers: Number Lines

Male passenger, dark hair, dark jacket, red Lee Cooper top: How much I owe you?

Driver, dark hair, black suit and tie, white shirt: That will be £7 please.

Driver, dark hair, black suit and tie, white shirt: 10.

Driver, dark hair, black suit and tie, white shirt: There you go £3 change, thank you.

Driver, dark hair, black suit and tie, white shirt: Thank you very much sir.

Male, dark hair, dark shirt: If I applied for a job and the pay was £250 after tax and my rent was £100 I would subtract £100 from £250 which would leave me with £150.

Female, blue crochet hat, grey coat: I have six grandchildren under the age of 10 so I give them £5 every month of my pension.

So that's five sixes are 30.

Number lines are a great way to visualise addition and subtraction on paper.
