At the meeting last week, I presented a couple of slides outlining the different variables that can be changed to develop activities. For example, the size of the field (length/width), the number of goals, the number of players on each team and the number of neutrals. I put together a single slide with this information:

I'm going to put together a more detailed article which describes these variables in more detail, with examples, and how they can be used to create activities for different themes and coaching points.
Please let me know if you have any questions.
