This modern classic by Paul and Henrietta Stickland is a brightly coloured rhyming dinosaur story. Endorsed by the American Natural History Museum for its accurate depiction of the dinosaurs this is a fun story of opposites that pre-school children love. The activities we have made include a matching activity, measuring long and short items, draw a dinosaur, learning to recognise shapes and colours, sorting items into big and little and a simple counting activity.
