Students were given records from the Guiness Book of Records and in groups of three had to replicate the measurements AND fill in the missing gaps thinking about possible scales. I was very impressed with the creativity given the limited size and colours of the chalk sticks. The sizes of some of these animals were positively mammoth. The accuracy was uncanny given students only had one hour and twenty minutes to consult with each other, sketch out preliminary measurements, draw and shade. Amazing team work! The drawings were enjoyed by all students and staff who visited the courts at lunch time and throughout the following day. The students then sat or laid next to their creations to get a real feel for the size of them! I love their impersonations of the animals.
