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.
