A directory of useful objects found on the web for teaching Maths.

How a science teacher presents scientific numbers – presented by a young energetic science teacher. Could either show the video or “borrow” the ideas on showing mass of the sun and mass of a proton as your lesson hook. Good question at the end for students to work out.see details …

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.see details …

How to instructions to set up a fun angle sum of triangles activity on your Interactive White Board. Students love building the triangles once they have seen you do it once and will try many different triangles to test the idea. Easy to extend to quadrilaterals.see details …

Photographs and analysis of an 1800 BC Babylonian table showing the diagonal of a square and ancient knowledge of the value of square root of two – expressed in base 60. A great extension resource. No previous knowledge of Babylonian required, but will make more sense if students know about different number base system. Full mathematical analysis on the site.see details …
