The Shapes Resource on the Birmingham Grid For Learning website is an Interactive site for reviewing both 2D and 3D shapes.
The site does a good job defining and introducing 2D shapes and, the 3D shape section, is one of the best resources for understanding 3D shapes.
Investigation of 3D shapes includes an interactive 3D model of each of the 3D shapes that learners can control by touching on the control buttons.
In addition, each 3D shape has an accompanying net that practitioners or learners can print out and construct individual 3D shapes.
This is a great resource to share with other functional skills / functional maths practitioners.
