Your students have mastered reflections and rotations in 2D, they are getting a bit cocky, they are thinking maths is easy. Well, let’s see how they cope with another dimension!

Autograph Video 35 – Planes of Symmetry
We make good use out of our cube again this week, this time by taking a look at the suprisingly tricky question of: “how many planes of symmetry does a cube have?”. Autograph’s 3D modeContinue reading
Autograph Video 34 – Pythagoras and Trigonometry in 3D
Let’s put last week’s cube into good use by looking at how we can use it to help illustrate the difficult topics of Pythagoras and Trigonometry in 3D
Autograph Video 33 – Cubes and Euler!
This week we learn how to construct a 2x2x2 cube in Autograph, which will come in very handy when we come to look at Pythagoras in 3D, Planes of Symmetry and Vectors in the nextContinue reading
Autograph Video 32 – Autograph in 3D
In preparation for the next few videos, we take a look at some of the important tools needed for getting the most out of Autograph’s unique 3D engine
Autograph Video 31 – More Vectors in 2D
This week we take a look at how we can make the study of vectors in 2D more dynamic, which culminates in a suggestion for a nice little starter activity that you can try onContinue reading
Autograph Video 30 – Vectors in 2D
This week we look at how we can use Autograph to model Vectors in 2D, including the multiple of a vector and adding and subtracting two vectors
Autograph Video 29 – Finding the Line of Best Fit
Following on from our work on Scatter Diagrams, we take a look at how the Line of Best Fit is calculated. This provides a valuable link from Key Stage 4 maths to A Level StatisticsContinue reading
Autograph Video 28 – Scatter Diagrams
Seeing as we are now experts with straight line graphs, this week we look at how we can use Autograph to study Scatter Diagrams, Lines of Best Fit and Correlations
Autograph Video 27 – The Gradient Tool
Following on from the last couple of weeks where we have looked at straight line graphs, this time we take a look at Autograph’s excellent Gradient Function. We see how useful it can be forContinue reading
Autograph Video 26 – Parallel and Perpendicular Lines
This week we follow-up our work on straight lines with a look at how you might tackle the topics of parallel and perpendicular lines on Autograph
Autograph Video 25 – Straight Line Graphs
Here we look at two different approaches to investigating the equations of straight lines on Autograph, both of which make good use of Autograph’s excellent dynamic textboxes, and one which uses the Constant Controller
Autograph Video 24 – Easter Special
Egg-sactly what you need this time of year – an Easter themed Autograph video. Here we take our first proper look at Autograph’s very impressive 3D engine and how you can use it to createContinue reading
Autograph Video 23 – Two Tangents Theorem
In a jam-packed edition of Mr Barton’s Autograph Videos we look at all things to do with Tangents, including the Two Tangents Theorem. This also leads us to discover a slick way of marking theContinue reading
Autograph Video 22 – Alternate Segment Theorem
This week we look at our fourth Circle Theorem – the notoriously difficult Alternate Segment Theorem. Can Autograph help us understand when this theorem works and when it doesn’t? There is also a look atContinue reading
Autograph Video 21 – Angles in the Same Segment
This week we look at our third Circle Theorem – the classic Angles in the Same Segment Theorem. There is also a quick demonstration of how to set up a nice looking label for points,Continue reading
Autograph Video 20 – Animation Special
In a special edition of Mr Barton’s Autograph Videos we look at the use of Autograph’s very impressive Animation function and how you might use it in the context of angles, points and transformations.
Autograph Video 19 – Cyclic Quadrilateral
This week we look at our second Circle Theorem – this classic Cyclic Quadrialteral Theorem. After quickly constructing and demonstrating the theorem, we also have a look at a nice little extension question involving parallelograms…
Autograph Video 18 – Angle at the Centre
Whilst we are on a roll with the Angle at the Centre Theorem, why not have a quick look at a nice little twist? We can use Autograph to set up some circumstances where theContinue reading
Autograph Video 17a – Angle at the Centre
This week we take a look at how to construct Circle Theorems using Autograph, beginning with the Angle at the Centre Theorem. We also see how understanding this theorem leads us to another theorem forContinue reading
