A Tarsia activity by Alan Catley. A great way of introducing the Factor Theorem but it took a long time to ensure that this is a unique solution! i.e. (x-1) is only a factor of one of the given functions etc. A wonderful group activity used in conjunction with a paused slow plot of y = 2x³ + x² – 4x – 3 on Autograph (at approx x = -2) where does this graph cut the x-axis? etc. The group will have to share the work out which means they discuss and share each other’s answers but the more they do the easier the puzzle gets. The ‘Start’ is a trivial one deliberately!

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.

Douglas Butler, the creator of Autograph, has produced 7 high quality tutorial videos to help you get the most out of the software. In this tutorial we have a look at Autograph's uniquely useful onscreen keyboard: for controlling Autograph, entering mathematical notation and changing languages. Also available on TES are my own weekly set of Autograph videos, and lots of Autograph Player Activities that don’t even require Autograph to be installed!

A worksheet for the well known knights move investigation. This is suitable for KS3 and KS4 students. The investigation involves looking at patterns and finding a formula to solve the problem. The activity is good revision and practice of knowledge in number patterns. It also develops good thinking skills. An extension is included for those students who are at a higher level ability.
