Tired of my annoying voice on these videos every week?... well, I’m pleased to say that this time I am handing over to my special guest, Douglas Butler, the creator of Autograph. Here Douglas shows you an interesting and engaging way of using Google Earth and Autograph to investigate gradients in real life. We start with a runway and end up taking a bike ride around Bolton. Lovely stuff, Mr Butler. I must get some music in my videos…

The 17th in a series of videos where each week I visit my favourite mathematics websites. iTunes U is a feature of Apple’s iTunes service where universities and education providers from all over the world have uploaded complete courses, with videos, notes, homeworks, on a whole variety of subjects, all completely free. Mathematics is really well represented. Here we take a look at a Statistics course from Harvard, and then at an excellent series of puzzles from Cambridge called Quite Easily Done (QED). This is a fantastic resource with potential to help both teachers and students.

The 17th in a series of videos where each week I visit my favourite mathematics websites. This week it is the turn of the Murderous Maths Website, which is the online home of the excellent Murderous Maths series of books. Just like the books, this site is absolutely crammed packed full of fascinating maths tricks, features and activities. I pick out a couple of my favourites, and also suggest a way that this website could be used for an interesting maths project with your pupils.

The 53rd in Mr Barton's Autograph Video tutorial series. Following on from our work on worksheets last week, this time we take a look at how Autograph can be used to very quickly create an incredibly flexible number line. This can then be used in class to help with the teaching of topics including place value, scales, sequences and negative numbers. Clicking on the web-link you can see all the videos in this series.

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 52nd in Mr Barton's Autograph Video tutorial series. Just a quickie here about how you can use Autograph to add that finishing touch to your perfect worksheet. Whether you want a lovely set of axes, some square paper, or some old fashioned graph paper, Autograph can satisfy your needs. We also look at a handy way of getting the size of the grid and the number range just right! Clicking on the web-link you can see all the videos in this series.

The 15th in a series of videos where each week I visit my favourite mathematics websites. Anyone who knows me or has watched my videos will know I am slightly obsessed with Statistics. My teaching of statistics has been revolutionised by Gapminder World and Guardian Data Blog, and now here comes another absolutely fantastic statistical website. With Nationmaster you can very quickly and clearly make comparisons between countries using thousands of interesting, up to date statistics.

The 51st in Mr Barton's Autograph Video tutorial series. Following a request from Science teacher Mr Richardson, here is a video explaining how you can use Autograph to fit functions to various data sets. It doesn’t matter if the relationship in your data is linear, quadratic or exponential decay, you can be sure that Autograph can handle it. Clicking on the web-link you can see all the videos in this series.

The 14th in a series of videos where each week I visit my favourite mathematics websites. It’s that time of the year where you may be tempted to throw a little bit of a… sharp intake of breath… “fun lesson” into the mix, and in my opinion there is no better fun lesson that one involving a quiz. Here are a few ideas and resources to help you put together an award-winning Christmas Quiz that might just make those last few lessons pass a little quicker. Merry Christmas and I will return with more videos in the new year.

The 13th in a series of videos where each week I visit my favourite mathematics websites. We return to the NRICH website to have a look at their annual offering of an advent calendar. But this is not your usual advent calendar because behind each door instead of a chocolate treat you will find… a mathematical treat! One lovely problem for each of the days leading up to Christmas. NRICH produces the goods once again. Ho, ho, ho!

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.

The 50th in Mr Barton's Autograph Video tutorial series. In the final Autograph Video of 2011 we take a look at some of the lovely shapes you can make using Volumes of Revolution. We hint at how it is possible to derive the formulae for some common 3D objects (for more on this see Mr Barton’s “Autograph Activities” textbooks!), how you can create volumes around the y-axis, and finally we look at some of the fascinating shapes you can form with areas between curves and lines. Plenty to keep you busy until the end of the year. Clicking on the web-link you can see all the videos in this series.

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.

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.
