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? 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

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! 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 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.

MEI has kindly shared the following resources to support the use of ICT in A/AS Level maths. These are practical activities that look at how we can use Autograph to enhance the study of differentiation and integration (calculus), predominantly at AS level. These are ideal for use in a computer room or for students to investigate at home. The pdf file contains full instructions and challenges, and the attached Autograph and Excel files can be used to demonstrate and consolidate understanding back in the classroom. Please click on the web-link to find out more about the work of MEI.

A presentation jam-packed full of revision notes and questions.

An Autograph Player activity designed to investigate cumulative frequency diagrams / curves. You can use this activity on the interactive whiteboard, or for your students to investigate on their own. Autograph does not need to be installed to use this activity (so your students can even use it at home), but you will need to install the free Autograph Player add-on (instructions given after clicking the link). For a full list of Autograph Activities, please click on the other web-link.

A video tutorial on how to use autograph for the geometric series at A Level. The 42nd in Mr Barton's Autograph Video tutorial series. Continuing our theme of all things statistical, this week we take a look at how Autograph might be used to introduce students to the concept of the Geometric Distribution, with a little helping hand from the Animation Controller! Clicking on the web-link you can see all the videos in this series.

A bingo game to test pupils' knowledge of indices.

A presentation covering the nearest neighbour, lower bound and tour improvement algorithms.

A video from the Autograph team. How can we find the area A under the curve y = f(x) between x = a and x = b? Clicking on the web-link below takes you to all the videos in this series.

A tutorial video from the Autograph team. A simple visual introduction to differentiation in calculus. Ideal for teaching C1. Clicking on the web-link below takes you to all the videos in this series.

A Tarsia activity by Alan Catley. These three activities basically cover most of the skills required to answer questions on this topic. Credit for these ideas goes to the Bring on the Maths activities on this topic but most of the questions in the three activities come from past papers. Perhaps a bit of Tarsia ‘overkill’ on one topic but it works really well.
