### Pizza Portions

My friends and I love pizza. Can you help us share these pizzas equally?

### Pies

Grandma found her pie balanced on the scale with two weights and a quarter of a pie. So how heavy was each pie?

### Red Balloons, Blue Balloons

Katie and Will have some balloons. Will's balloon burst at exactly the same size as Katie's at the beginning of a puff. How many puffs had Will done before his balloon burst?

# Balance of Halves

##### Stage: 2 Challenge Level:
We've had one way of doing it using a weight on the $\frac{1}{2}$ peg. How could you balance 7 using $1\frac{1}{2}$? Can you carry on going along the balance like this trying the "half numbers" in turn?

How will you make a note of what you have done?

How will you know that you have got all the different ways?
