Getting Better at Group Work Upper Primary

Working on a problem in a group gives you chance to discuss your ideas and further your thinking. Three or four brains are usually better than one! These activities will help you improve your group-working skills.

En-counters 
Age 5 to 7
Challenge Level Yellow star

This task requires learners to explain and help others, asking and answering questions.

Counters in the Middle 
Age 7 to 11
Challenge Level Yellow star

This task depends on groups working collaboratively, discussing and reasoning to agree a final product.

Arranging Cubes 
Age 7 to 11
Challenge Level Yellow starYellow star

A task which depends on members of the group working collaboratively to reach a single goal.

What Shape? 
Age 7 to 14
Challenge Level Yellow star

This task develops spatial reasoning skills. By framing and asking questions a member of the team has to find out what mathematical object they have chosen.
