Circumference of Circles - 4 activities

Using co-operative learning strategies I set up these 4 stations for pupils to rotate round. The fourth can be found here: http://www.tes.co.uk/teaching-resource/Discovering-Pi-and-amp-Circumference-Activities-6168593/ (the red/amber/green worksheets).\nFor the playing cards activity: give pupils pack of cards and they can deal out cards/cut the deck/etc. and then answer the corresponding question on the sheet.\nThe 'connect thoughts&' task is adapted from here: http://www.tes.co.uk/teaching-resource/Scottish-higher-functions-connect-thoughts-6296762/
