So far there are six different maths topics here....

In reverse time order....

6) February 2009: Factor finder page: I've wanted to get a decent factor
finder running, using JavaScript. for a while. At last it's working how
I wanted it too! It's **here**

5) December 2008: I have put the questions & answers from the YBMA
quiz onto **
this page... **

4) October 2008: Because I was giving the Retiring President talk at the
Yorkshire Branch of the Mathematical Association (more YBMA info **
here **), I looked again at a couple of
investigations; first,** 'Moves'**,
a nice, accessible activity.

3) Another investigation I really like is **'Perfect
Numbers'** - my first as a student teacher in 1986,
using a very inefficient factor finding program on a BBC Micro. The **first page** is
quite nifty at perfect number checking, using JavaScript. The second is
a **solution**,
presently OK mathematically, but the layout is very very rough!

2) October 2007: **Dynamic
Geometry & Circle Theorems**

I wrote these pages after noticing that one of the options in ** Geogebra **(a
free dynamic geometry package) is 'export the Dynamic Worksheet as a
web page' You can use them to work out what the circle theorems are, or
the last page has eight theorems and diagrams as a reference. What I
like is that because Geogebra is a dynamic geometry package, you can
move points around and see what happens, changing angles, altering the
size of the circles, etc.

I've updated the pages this year [2013]. The link is **here**

1) March 2007: First of all, **MASC
- Mildly Amusing Statistical Card game.**

It's a pleasant way to practice working out range, mode, median
& mean. I suppose it isn't particularly valid to add up all
these, but it is way of generating points, and of course, points mean
prizes!! There are a couple of pages **here**.
The first gives the rules, the second has an example game.
