A simpler version of the puzzle. Print out or just project on the board for whole class discussion.

A tutorial on using Autograph to work with grouped data.The fifteenth in Mr Barton's Autograph Video tutorial series. In our final look at data for a while (you can have too much of a good thing) we tackle an issue with commas and how to alter the sizes of your groups. 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.

The 9th in Mr Barton's Gapminder World Video series. In a video dedicated to Chris Holden, Amy Holden and their beautiful new baby daughter Isabelle Rose Holden, this week we look at some time series data on population growth rates around the world. How does the growth rate of the UK and USA compare to that of Qatar and Kosovo, and what on earth is going on in the Cayman Islands?

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 Tarsia activity by Alan Catley. Please Note: This Tarsia contains images and the links to these images are broken when the Tarsia is copied. Before using this jigsaw you will need to paste the images into the correct positions on the Input screen. This activity involving images of lines intersecting circles and corresponding pairs of simultaneous equations can be used in a variety of ways.

The 11th in Mr Barton's Gapminder World Video series. In this video, we fuse together two of my favourite things - Gapminder World and Autograph. We see how we can process the data from Gapminder using Autograph's powerful statistical engine in order to anyalse the strength of correlation. More statistical diagrams next week!

I know, I know, guilty as charged! This week’s Web Whizz video features my website. However, hopefully you will forgive me when you see the brand new and completely free Autograph Player activities that are now available. Unlike Autograph files, these activities do not need the software installed, which means you can use them completely freely to demonstrate topics in class, or set them as homework assignments for your students. Here we look at activities about transformations, angles, circle theorem, battleships and scatter diagrams.

A video tutorial from the Autograph team on Linear Programming. Using Autograph to visualise the solution to a linear programming problem. Clicking on the web-link below takes you to all the videos in this series.

The 5th in Mr Barton's Gapminder World Video series. What is the relationship between a country's wealth and their children&'s maths scores? Which country&';s children perform best at maths? And finally, can we use this data to make a case that boys are better at maths than girls?

Worksheet for the well known flowerbed investigation.

Gapminder Video 6 The 6th in Mr Barton's Gapminder World Video series. Is there a relationship between the wealth of a country and it's growth rate? Do rich counties keep getting richer, or do poorer countries grow faster as they have more capacity and potential? And what on earth is going on with China? As ever, there is only one way to find out!

A Collective Memory activity on Trigonometry and Pythagoras. For more information and ideas about how to use this resource, and links to my full index of Collective Memory resources, please visit http://www.mrbartonmaths.com/collectivememory.htm

Have a play around with this task, and please share any questions, extensions, simplifications, modifications, or lines of inquiry in the comment box below. The idea is to collect loads of suggestions that can then be used for effective differentiation. The full set of these tasks, along with additional notes, can be found here: http://www.mrbartonmaths.com/richtasks.htm

A video tutorial covering biased dice and probability. Ideal for KS3, GCSE and A Level maths. The 40th in Mr Barton's Autograph Video tutorial series. This week we take a look at how Autograph can be used to introduce students to the concept of experimental probability. You can very quickly set up a probability distribution function of your choice (fair dice, biased dice, numbered balls in a bag, you name it!), take samples of varying sizes, and create diagrams from the data.

A video tutorial on how to use Autograph to demonstrate integration, the Trapezium and Simpson's Rule. A good guide on how to use the software to show your students the origins of these techniques rather than just showing them the formulae. The 46th in Mr Barton's Autograph Video tutorial series. This week we move from differentiation to integration by taking a look at how Autograph can be used to introduce students to the concept of the area under the curve. The good news is that Autograph can easily and clearly illustrate estimating the area using rectangles.

The 66th in Mr Barton's Autograph Video tutorial series. The second of the Autograph Puzzle Trilogy! Here we look at another a lovely pencil and paper puzzle inspired by Don Steward’s amazing Median Maths Blog. Students are given four co-ordinates and asked to consider the shape that would be formed by joining up the midpoints of pairs of these co-ordinates. What type of quadrilateral is it? How do they know? We can then turn to Autograph to construct the puzzle and investigate it even further. Click on the link to see all my Autograph videos

UPDATE: Supporting worksheet by Brian Arnold! :-) The 60th in Mr Barton's Autograph Video tutorial series. In this video we take a look at an activity I like to use with my classes called Co-ordinate Battleships. I use this either to revise the equations of straight line graphs or even to introduce the topic. Teams take it in turn to launch their missiles (in the form of straight line graphs) in order to sink the ships (the co-ordinates). We look at how you can easily create this page on Autograph, and then some possible extension work after the sea battles are over.
