 Key Stage 1     Solve it...!      Some puzzles for you to solve!

Which are the numbers you can make be throwing 2 dice (1 to 6) and adding to the numbers you get?
Try the same activity with 2 different dice.
You can use the dice on the Interactive Lighthouse.

 Start at 1 and keep doubling. Will you ever reach 400? How many ears would 50 children have? How many toes would 100 children have?

 Key Stage 2     Solve it...!     The Price of TV

Your parents would like you to watch less television so they have struck a deal with you. They give you £10 at the beginning of the week. They allow you to watch one hour of television every day for free. For every half hour you watch past that you must pay half of your remaining money. When you have spent all of the £10 you must turn off the television for the rest of the week.

How many hours of television can you watch in a week? This table may help:

 Starting amount Extra (hrs.) TV watched Money left £10 ½ 1 1½ 2 2½

Think of how much television you watch. Would you have any money left? What would you spend it on.
