Upper Primary Group-worthy Tasks

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 upper primary activities have been created specifically with group work in mind.
