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.

Earliest recommended Year group: Year 8. Bisect the sides of a quadrilateral to get a parallelogram. All quadrilaterals are different but all parallelograms are identical. The grid allows easy bisection 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!

Earliest recommended Year group: Year 9. Bisect the sides of a quadrilateral to get a parallelogram. All quadrilaterals are different but all parallelograms are identical. A compass will be needed to bisect the sides. 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!

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?

The 33rd in Mr Barton's Autograph Video tutorial series. This week we learn how to construct a 2x2x2 cube in Autograph, which will come in very handy when we come to look at Pythagoras in 3D, Planes of Symmetry and Vectors in the next few weeks. There is also a nice little link to Euler's famous formula.

A video from the Autograph team. We begin by plotting the sine curve and its gradient function in degrees and use this to motivate the introduction of radians. Clicking on the web-link below takes you to all the videos in this series.

A Tarsia activity on Times Tables. These type of activities can be used to consolidate understanding of a given topic, and foster positive group work and co-operative learning. For more ideas on how to use these types of activities (including twists!) and to download the latest version of the wonderful free software to open this resource (and create your own), just click on the web-link. If you have any comments, or spot any (non deliberate!) mistakes, please share them below. Many thanks to all the teachers who have helped me assemble these Tarsias over the years.

In a special 'loved-up' edition of Mr Barton's Autograph videos, we look at a romantic (mathematical) alternative to chocolates and flowers to send to the love of your life to let them know you care. Happy Valentines Day! 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 19th in Mr Barton's Autograph Video tutorial series. This week we look at our second Circle Theorem - this classic Cyclic Quadrilateral Theorem. After quickly constructing and demonstrating the theorem, we also have a look at a nice little extension question involving parallelograms...

Earliest recommended Year group: Year 7. Based on the nRich task. Using their own numbers (following a rule) the pupils form fractions and carry out operations on them. All answers are the same. 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!

A video from the Autograph team. The Binomial approximation is often used for approximating powers of numbers close to 1, but how close to 1 do we need to be in order for the approximation to be any good? Clicking on the web-link below takes you to all the videos in this series.

A video from the Autograph team. In this activity we explain how to enter equations and introduce Slow Plot, the Scribble Tool and the Constant Controller. Clicking on the web-link below takes you to all the videos in this series.

The ninthvideo in Mr Barton's Autograph tutorial series. This time we look at the basics of measuring angles in 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.

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! 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 video from the Autograph team. In this activity we will demonstrate a link between the graphs of trigonometric functions and the unit circle. Clicking on the web-link below takes you to all the videos in this series.

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 the TI-Nspire (graphical calculator) to enhance the study of e, ln and functions predominantly at A2 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 you can download all the supporting TI files by clicking on the weblink.

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 Geogebra to enhance the study of e, ln and functions, 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 Geogebra 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.

The 17th in Mr Barton's Autograph Video tutorial series. This week we take a look at how to construct Circle Theorems using Autograph, beginning with the Angle at the Centre Theorem. We also see how understanding this theorem leads us to another theorem for free! Autograph's dynamic nature makes it perfectly suited to demonstrating circle theorems to your students.

The 7th in Mr Barton's Gapminder World Video series. Which country in the world is the highest emitter of C02 per person and how has this changed over time? As ever, there is only one way to find out and you might just be surprised at the results!

The 12th in a new series of videos where each week I visit my favourite mathematics websites. I am always on the look-out for short, snappy activities that are related to things going on in the real world to hammer home the relevance of maths to my students. Well, for that aim this amazing website is simply a Godsend. Each day new activities appear based around current news stories. Whether it be tennis, the new host of Countdown or the destruction of the Brazilian Rainforest, you can be sure that MathsFlash has a starter activity lined up for you. Enjoy.
