Having tackled the activities which are designed to improve group-working skills, why not encourage children to put their skills to good use in other mathematical contexts?  Although almost any NRICH activity could be tackled in a group, these lower primary activities have been created specifically with group work in mind.

### Thirsty?

##### Age 5 to 7Challenge Level

Can you lay out the pictures of the drinks in the way described by the clue cards?

### Sort Them Out (1)

##### Age 5 to 7Challenge Level

Can you each work out the number on your card? What do you notice? How could you sort the cards?

### Even and Odd

##### Age 5 to 7Challenge Level

This activity is best done with a whole class or in a large group. Can you match the cards? What happens when you add pairs of the numbers together?

### It's a Fence!

##### Age 5 to 11Challenge Level

In this challenge, you will work in a group to investigate circular fences enclosing trees that are planted in square or triangular arrangements.

### Sorting the Numbers

##### Age 5 to 11Challenge Level

Complete these two jigsaws then put one on top of the other. What happens when you add the 'touching' numbers? What happens when you change the position of the jigsaws?

### Jig Shapes

##### Age 5 to 11Challenge Level

Can you each work out what shape you have part of on your card? What will the rest of it look like?
