A video from the Autograph team. One of the classic 'goat grazing a field' geometry problems demonstrated. Clicking on the web-link below takes you to all the videos in this series.

The 18th in Mr Barton's Autograph Video tutorial series. 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 the theorem doesn't seem to work. Has maths been broken, or can your students figure out what is going on?...

The 17th in Mr Barton's Autograph Video tutorial series. 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 for free! Autograph's dynamic nature makes it perfectly suited to demonstrating circle theorems to your students.

A fascinating tutorial video from Douglas Butler who uses Autograph to investigate why the optimal angle for a shot put to be thrown is not 45 degrees but 31! To see all the videos in Mr Barton’s Autograph Video series, just click on the web-link below. Ideal for KS3 and KS4 students.

An excellent tutorial video from Douglas Butler which reveals a simple and highly effective way of demonstrating to students where the least squares regression line comes from. To see all the videos in Mr Barton’s Autograph Video series, just click on the web-link below.

A video tutorial exploring torus in Autograph. What do you get when you rotate the equation of a circle about a line in 3D?... there is only one man to tell you the answer to that - Mr Douglas Butler. To see all the videos in Mr Barton’s Autograph Video series, just click on the web-link below.

A video tutorial on how to use Bivariate data in Autograph. This time Douglas Butler takes us through how we can do scatter graphs and lines of best fit on Autograph by looking at an interesting relationship between the weights of babies and the gestation period.

A tutorial on how to use the Normal Distribution in Autograph. Douglas Butler, the Autograph creator, looks at a really interesting way of how we can fit a normal distribution to data using Autograph. To see all the videos in Mr Barton’s Autograph Video series, just click on the web-link below.

A video tutorial on how to use autograph for reflections. A special treat from the Autograph guru Douglas Butler who shows us some really nice things you can do with reflection on Autograph, including looking at the beauty of nature and the talent of the Red Arrows pilots.

The sixteenth in Mr Barton's Autograph Video tutorial series. A great tutorial for guidance on using Autograph to work with raw data. I know I said last week was the last data one, but a request came through on the emails, so I thought I had best cover it whilst we are on a roll! So, this week we look at different ways of entering grouped data, another way of comparing data, and we take another look at the Results Box.
