Having talked about random name generators – a quick reminder that SMART notebook has a good tool for generating random groupings which can fit well into a SMART presentation. The SMART generator is available straight from the Lesson Activity Toolkit in the SMART notebook programme itself. Well worth looking at if you teach a subject in which you are often dividing students into groups. All groups can be set up at the begininng of the year (as with random name generators) and saved so you can bring them up at any time.
As with most of these things there are lots of other useful tools for this which are based online or are apps which can be downloaded.
