### Number Round Up

Arrange the numbers 1 to 6 in each set of circles below. The sum of each side of the triangle should equal the number in its centre.

### Junior Frogs

Have a go at this well-known challenge. Can you swap the frogs and toads in as few slides and jumps as possible?

### Jumping Squares

In this problem it is not the squares that jump, you do the jumping! The idea is to go round the track in as few jumps as possible.

# All Change

##### Stage: 1 Challenge Level:

Here are three challenges for you to try.

In each case, the idea is to complete the game in as few throws of the die as possible.

Let us know how you get on! Do you think it would be possible to do it in any fewer? Why?

Which game needed the fewest number of moves? Will that always be the case, do you think?

Why?

Challenge 1

Throw the die and click on that number of plugs.

How many throws do you need to change the colour of all the plugs?

Challenge 2

This time when you throw the die you must click on that number of plugs but they must all be in the same row.

How many throws do you need to change the colour of all the plugs?

Challenge 3

Now when you throw the die, you click on that number of plugs all in the same row and you must finish a row before starting a new one.

How many throws do you need to change the colour of all the plugs?
