# Shape maker: complex objects 1

TLF ID L1061

Transform 2D shapes to make a stack of 3D objects. Start with a shape such as a crescent, semicircle, circle, triangle or rectangle. For example, spin a semicircle around its straight edge to form a sphere or extrude it to form a half cylinder. Choose a shape and imagine it being spun around an axis or extruded. Picture which 3D block your 2D shape will make. This learning object is one in a series of six objects.

#### Educational details

Key learning objectives
• Students see 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.
Educational value
• Illustrates the relationship between a 2D shape, its transformed 3D shape and the cross-section of the 3D shape.
• Provides six 2D shapes, spinning and extruding transformation actions, and six axes to spin around.
• Enables students to see the effect of different 3D transformation actions on the same 2D shape.
• Includes the option to print a worksheet with the 3D shapes created by the student.
