Using NRICH Solutions with Your Colleagues

In our Celebrating Solutions Feature, we suggest that solutions published on the NRICH website can make a useful teaching resource in their own right.  You could use the published solutions with colleagues, in a staff meeting for example, or with your own children as part of a lesson.  

The solutions to the tasks below lend themselves to use during a staff meeting to facilitate conversations about assessment.  For more information about the ways in which you might do this, please see the article included in the feature.
