3-D Shapes
An interactive flash widget that looks at 2D and 3D shapes. The 3D Shapes section steps through 1D, 2D then 3D. It also includes good pictures of various solids and their can be spun around.
A centre for ants!?
A clip from the movie “Zoolander”. Consider for use as an introduction to Scale.
A Tangled Web, practise solving angles
Help Itzi the spider climb the clock to rescue his family! Solve cunning angle puzzles to reveal a path through each level’s maze of tangled webs and reach the goal. It’s sure to make your head spin!
- Basic angle rules
- Parallel lines
- Polygons
- Circle theorems
Airplane infront of the moon
WCYDWT? This image is a great stimulus to build a similar triangle problem. Students could use the internet to find out various dimensions and demonstrate or calculate a missing variable such as: how high was the plane flying. See also http://www.iceinspace.com.au/iotw.html?iotwid=137 and forum for more details. Could load image into GeoGebra for more accurate modelling.

Angle Measure
“An interactive whiteboard resource to demonstrate the measuring of angles to a class.”
