The resources below have all been created using Geometer's Sketchpad, although the ideas are of course transferable to other dynamic geometry software. Each file is produced as a GSP file and a copy of the dynamic image is included in the MS Word file.
Other electronic-based resources are listed here - mostly spreadsheets or powerpoints. Many of these are now accessed through the relevant interactive scheme of work.
Construction: A slideshow to demonstrate one historical example of accurate mathematical constructions: rose windows
Mensuration: A 'Who Wants To Be A Millionaire' activity
Nets: A quick starter - complete the diagram to make a net of a cube
Pythagoras' Theorem: A spreadsheet that identifies many Pythagorean triples. If pupils know how to use conditional formatting, this is a lovely activity for them to try.
3D shape: A mulitlink challenge - can students get the plan / elevations at the end?!
Paper Resources
Paper-based resources are listed here. Many of these are now accessed through the relevant interactive scheme of work.
Area: A totally mad area trick. Guaranteed to amaze!
Bearings: A trimmed down version of the topograph on the summit of the Malvern Hills. With a bearing protractor overlaid it is useful to introduce the concept of measuring bearings.
Congruence: Investigating the ways of splitting a grid into congruent pieces
Construction: Group activity involving construction of plans and elevations
Loci: Some practical loci problems. Good as an introduction.
Transformations: Investigating the effects of enlargement on area and volume.
Transformations: An introduction to translation including vectors
Transformations: A simpler version of the above sheet, this time no vectors
Transformations: A basic completing enlargements activity. The teacher needs to choose the center of enlargement to suit the ability of the group.
Transformations: A template for a measuring activity to enable pupils to discover how to carry out an enlargement when the centre of enlargement and scale factor are given
Trigonometry: Plotting the graphs of trigonometric functions
Volume: How many grains of rice fill your classroom?!
