Cuboid nets - make a mobile phone

Lesson allows students to design a mobile phone and make a net then build it, or they can use preprinted nets and add their own features, or they can make a fake life sized Blackberry or iphone. Suggest students use sellotape not glue as they are a bit fiddly as the shapes are quite slim. Hope you enjoy using this as much as I enjoyed making it! Please comment as if there is any interest I thought I may extend it to making packaging or slot cars or similar.
