NumberLoving Blog. The 16th in a series of videos where each week I visit my favourite mathematics websites. If one amazing mathematics blog wasn’t enough for you, well how about two! Following on from Colleen Young’s excellent blog (see Video 8) we now have Number Loving. This blog is simply rammed packed full of the latest mathematical news and developments. There are loads of free resources and lots of great ideas that the authors have kindly shared, all for free. It is definitely worth signing up to. Thank you Sharon and Laura!

The 49th in Mr Barton's Autograph Video tutorial series. Following directly on from Video 48, this week we look at how we can use Autograph’s unique 3D engine to demonstrate to students exactly where the formula for the volume of revolution comes from. This provides a nice insight into limits and the fundamental theorem of calculus. Clicking on the web-link you can see all the videos in this series.

Earliest recommended Year group: Year 11. This tests the pupils knowledge of straight line graphs and y=mx+c and the significance of gradients of perpendicular lines. 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!

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!

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.

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.

The famous area puzzle where a square disappears!

The eleventh video in Mr Barton's Autograph tutorial series. Following a suggestion from none other than Autograph creator Douglas Butler, we take another look at some of the things you can do with Raw Data on Autograph, including quickly creating a data set. More stats to come next week! 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.

An Autograph Player activity designed to help investigate cumulative frequency diagrams and box and whisker plots / diagrams together. 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.

Earliest recommended Year group: Year 11. Measure the sides and angles and calculate the ratios. All ratios in the class are the same, yet all of the triangles are different This is from the “Something in Common” collection of resources by John Burke.

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. 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.
