I first heard about this on MFLresources before the summer holidays. I thought I'd give it go in September. It was so good I have done it with all my GCSE and Year 9 classes. I have also done it for an observation that went well.
I would like to thank Vincent at MFLresources for this fabulous idea, and have attached a photo of one the pupil books to give an idea of how it looks.
snowball = error
tree = accurate
penguin = good
penguin on skis = fab.
I began by giving out very few trees to encourage good accuracy, then there seemed to be a fight over who would get the first penguin.
To be honest the pupils seemed to really want to see my pathetic attempts at drawing a penguin on skis rather than wanting it for its own sake.
Really positive lesson.
