Jumping Squares

Jumping Squares

Jumping Squares printable sheet

This activity can be done alone or with a friend. The aim is to get to the end of the track in as few jumps as possible.

Here is the track of squares that you will be jumping on:

The numbers on each square are the numbers of squares that you can jump forwards or backwards when you are on that square. On the 'Start' square, you can jump forwards 1 or 3 squares for your first jump. If you land on a square with 1 and 4 on it, you can jump forwards or backwards either 1 or 4 squares.

If the square has 0 and 0 on it, you can't jump at all. You have to go right back to the beginning and start again!

Have a few tries at getting from the 'Start' square to the 'End' square by making these jumps. How could you count the number of jumps you are making?

What is the least number of jumps you can make to get round the whole track? Which squares do you need to land on?

Why do this problem?

This problem will encourage children to work systematically, and think and plan ahead. The activity can be done by one child working alone, but might be better if two work together.

Possible approach

You could start by looking at the first line of the track with the whole group. Explain the rules of the challenge and invite children to talk to a partner about what their first move might be.  Ask for some suggestions and encourage good explanations of their choices.  This initial discussion will allow you to reinforce the rules and make sure that learners do not count the square they are on when jumping forward (or back).

Key questions

Possible extension

Learners could make their own 'jumping squares' track for others to try or perhaps they could introduce a different rule using the same track.

Possible support

It might be that an adult could keep count of the number of moves made so this takes out one level of detail for the children to attend to.
