The class were playing a maths game using interlocking cubes. Can
you help them record what happened?
If you have ten counters numbered 1 to 10, how many can you put
into pairs that add to 10? Which ones do you have to leave out?
Can you create more models that follow these rules?
Cut out the square and the two pieces and try to make some shapes. (You could print off this sheet which contains four copies of the square.)
How will you record your findings?
How do you know you have found all the shapes?
