## Phoebe's amazing maths work

Today we will be following on from yesterdays lesson, finding the difference between two numbers.

**Task one**: count up to work out a small difference between two numbers

We can find the difference between two numbers by counting up on a number line or bead string, jumping to the next multiple of ten. This uses our known number knowledge.

Look at Task One photo. 42 - 36 = ?

Now have a go at answering the questions next to it.

**Task 2:** Work out change from 50p and £1 for items priced between 30p and 50p

Using the printable cards or by creating some of your own. Pick a picture card and write a number sentence to work out the change from 50p or £1 (Remember £1 is the same as 100p)

For example.

The hot dog picture is 38p. 50p - 38p = 12p

Draw yourself a number line to help work out the answer see **Task 2 picture.**

**Task three**: Look at these questions. Are they true or false? Do I need to do more than one operation to answer the question? This means I may have to add up before I take away. This is called a two step problem.

- I have £1.00 and I spend 62p. I am given 48p change. Is this correct?
- I have 50p to spend. I buy a sweet for 35p and get 15p change. Is this correct?
- I spent 32p on a cake, 42p on a bun. How much change will I get from £1.00?
- I spent 10p, 35p and 20p on pencils. I have £1.00. What change will I get.
