I really do not know what to say – thank you so much for this contribution. It only became apparent on Friday that some subjects might find it difficult to link it to their subject – including Maths. I thought it would be unlikely that anyone could help, given the short notice before the session on Monday, but you have saved the day! It will make my session tomorrow far more relevant – to be able to give examples from beyond geography. I’ll let you know how it goes. Thanks again, Jo

You’re very welcome Jo. It was an interesting activity and there’s a certain challenge to ‘will this work in Maths’. Hope it helps and look forward to seeing your grid. As for the speed factor – only in the world of twitter eh?
