### Are You a Smart Shopper?

In my local town there are three supermarkets which each has a special deal on some products. If you bought all your shopping in one shop, where would be the cheapest?

### Would You Rather?

Would you rather: Have 10% of £5 or 75% of 80p? Be given 60% of 2 pizzas or 26% of 5 pizzas?

### You Never Get a Six

Charlie thinks that a six comes up less often than the other numbers on the dice. Have a look at the results of the test his class did to see if he was right.

# The Magic Number and the Hepta-tree

##### Stage: 2 Challenge Level:

The Mathemagician needs to break a dreadful spell! Help him to find the magic number that will do the trick!

Here is the hepta-tree hung with silver balls.

Do you think the balls will have similar values?

Try estimating the amount on each ball.

In order to break the spell, firstly find the exact difference between the largest ball and the smallest ball.

Multiply your result by $244$.

Round this to a whole number and that gives us the MAGIC NUMBER!

Give this number to the Mathemagician and the terrible spell will be broken for ever!
