PowerPoint with opening question, quick triangle quiz, how to contruct a triangle with a protractor (Link to Mr. Reddy's Geometry Toolbox: http://www.mrreddy.com/geometrytoolbox.swf), differentiated mini-plenaries on constructing with protractor and then similar process for construction with a pair of compasses. The PowerPoint finishes with the opening question. Differentiated wrksheet for consoladation included. Any comments on how to improve, very welcome. Thanks.

Here is a collection of timers for use in any lesson. They are simple and (I think) quite attractive. No bumph, just timers with a couple of example slides. They range from 30 seconds to 10 minutes but can be extended very easily. Runs as PowerPoint so slides can be copied or objects copied for use in any lesson. Completely original and distributable material.

GCSE Similar Triangles. Whole lesson on Similar Triangles. Includes sort card activity, lesson plan and supporting PowerPoint. Teaches key words and also includes differentiated worksheet. It is quite simple. The PowerPoint begins with an opening question that students come back to at the end to show progression of learning.

Simple sort card activity. Students cut out and sort out the images of 3D shapes to their corresponding nets. Nothing fancy and not complicated.
