The 3rd in Mr Barton's Gapminder World Video series. Here we look at the relationship between the age women are getting married and their fertility rate, and we observe some startling results. Once again three countries are chosen for our focus: China, the UK and Algeria.

The 30th in Mr Barton's Autograph Video tutorial series. 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.

A special edition of Mr Barton’s Gapminder World Video series. This is a video that I created especially for Oxfam’s water week, and it looks at the different levels of access to water for counties all over the world.

The 2nd in Mr Barton’s Gapminder World Video series. Here we look at how the world has developed over the last two hundred years by focusing on the relationship between a country’s life expectancy and the average income of the country’s inhabitants. For the analysis we look specifically on three countries: China, Rwanda and the UK.

The 1st in Mr Barton's Gapminder World Video series. This is an introduction which takes you through how to access the Gapminder World website and how to use some of the basic tools, such as how to select different variables, highlight specific countries, and track changes through time.

The 29th in Mr Barton's Autograph Video tutorial series. 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 Statistics as Autograph is able to clearly demonstrate the method for finding the least squares regression line.

The 28th in Mr Barton's Autograph Video tutorial series. 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.

The 27th in Mr Barton's Autograph Video tutorial series. 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 for studying straight lines, and as a way of introducing older students to the joys of differentiation and calculus.

A Video Tutorial on using Autographs for parallel and perpendicular lines at KS3/KS4. The 26th in Mr Barton's Autograph Video tutorial series. 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. Below the video you will find an option to download it and play it on a larger screen, or by clicking on the web-link you can see all the videos in this series.

A great tutorial explaining how to use autograph to investigate straight line graphs. It is very clear and has lots of ideas as to how to use this software in class. The 25th in Mr Barton's Autograph Video tutorial series. 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.

The 24th in Mr Barton's Autograph Video tutorial series. 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 create planes and rotate curves around lines to make 3D objects. Happy Easter!

This video tutorial demonstrates how to use autograph for the two tangents theorem at GCSE. The 23rd in Mr Barton's Autograph Video tutorial series. 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 the intersection of two lines on Autograph and how to measure the length of line segments.

The 22nd in Mr Barton's Autograph Video tutorial series. 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 at how to construct tangents and a sneaky way of measuring angles.

A Collective Memory activity in PowerPoint on Area, Perimeter & Volume from Jane Hitchcox. This one contains deliberate mistakes and probing questions.

A few years ago I wrote a set of notes for pupils and put them on my website. The notes were supposed to be written in a pupil-friendly way, and different to notes students might find in textbooks or elsewhere on the internet. I have converted the notes to PowerPoint slides so you can download them, adapt them if needed, use them in revision lessons or perhaps give your students a set to take home with them to help them prepare for exams. The chances are there will be a few mistakes here and there, so if you spot any please email me & I will correct them. Hope they are of use!

The 21st in Mr Barton's Autograph Video tutorial series. 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, and a twist that you might want to try on your students.
