9SC Learn about ratio using photography

9 SC have completed an active learning challenge in which they enlarged a photograph from a film negative.

The challenge was to create the size of the photograph using a ratio of 1:20, starting with the dimensions of the negative.

Learning about negatives and film was in itself a retro challenge for some pupils but by the end of the lesson, each group had a clear understanding of another real life application of maths which had helped them grasp a concept. 

The results will be displayed on the board outside M1 if anyone wants to learn how to do it!
