Advert: Below you will find a certain number of dots. Have a very quick look at the dots above, then scroll down the page until you can’t see them any more Keep scrolling!!! KeepContinue reading
Autograph Video 71 – Find the Line
Here is a quick idea for an activity that should help your learners practise identifying the equation of a line from the points that lie on it. A line is constructed, and a point attachedContinue reading
Autograph Video 70 – Trig and Pythag – Part 3
All good things must come to an end, and the same is also true for our Autograph Trigonometric Trilogy! In this final video we go out with a bang by taking a look at howContinue reading
Autograph Video 69 – Trig and Pythag – Part 2
The second of the Trigonometric Trilogy! Following on from last week’s work, we take a look at how we can use Autograph to help students practise finding the sizes of missing angles in right-angled trianglesContinue reading
Autograph Video 68 – Trig and Pythag – Part 1
The first of the Trigonometric Trilogy! In this week’s video we take a look at a clever way of using Autograph to practice working out the length of missing sides using Trigonometry (sin, cos andContinue reading
Autograph Video 67 – Pizza Puzzle
The final part of the Autograph Puzzle Trilogy! This week we take a look at the “Pizza Problem” — what is the maximum number of pieces you can cut a pizza up into making straightContinue reading

Autograph Video 64 – Matrix Transformations
Should you find yourself needing to teach the transformation of matrices, it would be nice to have some dynamic geometry package to help you along the way through this very visual topic. This is whereContinue reading
Autograph Video 63 – Line Symmetry in Quadrilaterals
This is the much-anticipated(!) sequel to last week’s Line Symmetry in Rectangles. Here we look at how we might create an Autograph page to look at line symmetry more generally by allowing us to alterContinue reading
Autograph Video 62 – Line Symmetry in Rectangles
A common misconception amongst students (and myself, actually!) is that a rectangle has 4 lines of symmetry. In this video we look at how we can use Autograph to illustrate this concept in a simple,Continue reading
Autograph Video 61 – Circle Through 3 Points
I was surprised that one of my Year 13 students wasn’t aware of the lovely fact that you can draw a circle through any 3 points, so long as those 3 points do not lieContinue reading
