Mister Maker is very prescribed... Surely CD is able child initiated creativity rather than reproducing an adult design. Good creativity is about the children coming up with their own designs and discussing them. If you want to focus on creativity maybe try choosing a topic which inspires the children's imaginations to make/construct lots of different things. My class have really taken to our space topic this term and i've have some brilliant rockets, aliens, planets, outfits, using a wide variety of media - clay, salt dough, junk modellings, paint, chalk, collage, crayons, water colours, tissue paper. They also designed the spaceship role play from scratch including the outfits.
