A couple of weeks ago I started adding a selection of random items of news, suggested resources and so on to the end of a blog post, basically anything that had caught my eye that week (thanks to **Doug Belshaw** for the idea; I enjoy his weekly **Thought Shrapnel**). This week there seem to be several so I’ll make this week’s post a collection of such items.

- My Year 11 students (age 15-16) are studying for a second GCSE in Mathematics. We are using
**AQA’s Level 2 Certificate in Further Mathematics**, a course which we are all enjoying; it extends these able students and is excellent preparation for further study of the subject. We are currently looking at trigonometry and I want a good demonstration for graphing the sine function. Looking at various applets I came back to a site I use a great deal and have written about before,**John Page’s Math Open Reference.**Here you will find many very clear applets including exactly what I want, have a look at**Graph of the Sine function**. Note that is possible to display full screen which is great for the Interactive whiteboard. Drag the point A around and watch the graph and try Progressive mode. I have put the links for my students in**this post**.

- I really like the
**Grade that Question**resources by Zeb Friedman. See also many other useful revision resources on**Suffolk Maths.**

- I want to go to a
**UK Maths Museum**! Should I happen to be in Giessen (about 50km north of Frankfurt) I’d like to go to**now****The Mathematikum**. Failing that I could visit a**Virtual Mathematics Museum.**See also**this museum**from Count On.

- The Guardian Teacher Network has a new
**Maths hub**bringing together maths news and resources.

**Dilbert**makes me laugh!
