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.

The 11th in a new series of videos where each week I visit my favourite mathematics websites. Google can always be relied upon to come up with the goods, and this little website is no exception. Google have taken all of the 5.2million books that they have access to from the last 200 years, analysed all 500 billion words of them, and made it possible to search for the relative frequency of any of the words within them. So, how does garlic compare to onion over the last couple of centuries? How about radio, television and the internet? Lots of fun with numbers and graphs to be had here.

A video on how we can use autograph to manipulate continuous data. The thirteenth video in Mr Barton's Autograph tutorial series. In a jam-packed edition we start to look at how Autograph can group raw data for us and how this opens up a whole new set of possibilities in terms of mathematical diagrams, including cumulative frequency curves, histograms and stem and leaf. 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 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.

Earliest recommended Year group: Year 12. An integration activity around the area bounded by two parabolas. Some pupils are confused if the area straddles the x-axis. This activity addresses this. This is from the “Something in Common” collection of resources by John Burke. They allow consolidation of key skills, prevent students from copying each other (as all the questions are different), make marking and assessing easy for the teacher (as all the answers are the same!), and provide a lovely extra challenge for students as they try to figure out exactly what is going on! To access the full collection, and read John’s background notes, please visit: http://www.mrbartonmaths.com/common.htm

A GCSE and A Level tutorial video on how to use Autograph to teach the Binomial Distribution. The instructions and guide is very clear. The 41st in Mr Barton's Autograph Video tutorial series. In this video we continue our look at statistics and probability by seeing how Autograph can be used to introduce the concept of the binomial distribution. We look at the classic example of tossing a coin to create dot plots and box and whisker diagrams, and then we introduce a nice little twist...

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.
