Polygon Proofs
Use these triangles to make regular polygons and deduce all of the angles! Start with a puzzle and end with the proof for the interior angle of a polygon! This is a series of activities where you will...
Vectors and Transformations
Kaleidoscope
This is one of three activities, similar in nature, for exploring transformations. Mathematics has always been deeply dynamic and technology now allows us to explore mathematics through different dynamic...
Geometry
Giant congruent triangles
Constructing large scale triangles with playground chalk and looking for congruence! This activity is all about constructing triangles and finding out what details completely define a triangle to make...
Geometry
Similar Triangles Free
'Sort out the triangles so you can work out the missing lengths!' There are lots of things that we can do with the 24 triangles used in this activity (download and print below)! The simplest way to describe...

Making Indestructible Quadrilaterals Free
'Construct your own indestructible quadrilaterals based on your understanding of their fundamental properties' This is an activity in its own right, but does follow on really nicely from Indestructible...
Geometry
Indestructible Quadrilaterals Free
'Push, pull and stretch these shapes to find out which quadrilaterals they are!' Each of the shapes in this activity have been carefully constructed so that there are some properties that it ALWAYS has,...
Geometry
Impossible Diagrams
The aim of this task is to argue, conclusively, about whether or not the following shapes and diagrams can actually exist! To be successful, you will have to use what you know and can deduce about the...
Geometry
Impossible Triangles
Can these triangles exist? The main thrust of this activity is easily explained - What reasoning can you use to decide if these triangles can exist or not? (assuming that all lengths are rounded to the...
Number
Negative Indices/Exponents
The following contains 12 core questions, using negative exponents (indices, powers and exponents all mean the same thing (they are synonyms)) and 8 onscreen questions on EXTENDED to address the syllabus...

Inequality Pacman
If you want to describe a point you use coordinates (2,5), for lines you use functions: y=-3x+2, but what about whole "regions"? One way is to use "inequalities". An "inequal" function is one in which...
