Oh, how I hate Wednesdays!

Such a busy day! Wednesday and Thursday are heavy days as far as 'the post' goes, then I have the primary school running club. It should be a pleasure.......but today I feel inadequate and fed up with it all! I have a medium sized group - 12 - of mixed ages (4-11) There are 2 very disruptive children amongst them, and I find it hard to keep activities going well for everyone else. How do you super, saintly, primary school teachers do crowd control???
