# Shape Maker

Students explore the relationships between 2D shapes and 3D objects by visualising the movement (translation or rotation) of the 2D shape and predicting the resulting 3D object.

### Teacher notes

• Students are required to visualise the result from spinning or extruding 2D shapes.
• Students select from the shapes available then apply a spin or extrude action to it.
• Where students choose to spin the shape, they also select the axis for spinning (except in 'simple objects').
• Students are able to look at the cross section once the 3D object has been created.
• Printouts are available from all objects.

### Learning objects

 Shape maker: simple objects Students select either a square or circle. Students build a stack of eight objects, which can then be printed out. Shape maker: blocker Students select from a square or circle. They then predict the resulting 3D object. If the choice is correct, the transition from 2D to 3D is shown. Students build a stack of six objects they have created, which can then be printed out. Shape maker: stacker Students select from a diamond, circle and rectangle. The students predict the resulting 3D object. If the choice is correct, the transition from 2D to 3D is shown. Students build a stack of six objects they have created, which can then be printed out. Shape maker: complex objects 1 Students select from a diamond, circle and rectangle. The student builds a stack of 8 objects which can be printed out. Shape maker: complex objects 2 Students select from three more complex 2D objects: crescent, trapezium and rhombus. The student builds a stack of 8 objects which can be printed out. Shape maker: replicator Students are required to break down an object made of several 3D objects into its components, and then replicate these objects. Students identify a component, then select the 2D shape they want and the action to be taken on it (spin or extrude) to match the chosen 3D component. The interaction ends when the entire object has been replicated. Students can print the object they have replicated
