One of the most popular posts on this blog is the one on online whiteboards which has been updated recently. Using Screenr recently I was reminded how well it works. It is also possible to easily upload a Screenr screencast to YouTube.
This was part of some feedback on a homework task (Tethered Goat – see nrich version here).
The video has been uploaded to our class wiki (I use Wikispaces).
The wiki page includes advice on the features of a great solution, some questions for reflection and some images of student work.
Waldomaths by Ron Barrow has extensive resources for students to explore. These work well on the interactive whiteboard.
There are numerous applets for ages 11-16, also for ages 16-19.
I like using these in class as students can then experiment themselves at home.
A recent addition is this applet on fractions which allows students to study examples and see how to handle fractions.
The fractions A and B can be changed and students can see how to add, subtract, multiply or divide the two fractions.
I have used and like many of these applets - Circle Theorems for GCSE for example or the Normal Distribution in KS5 to show how the probability changes for different areas under the curve. (I have used this together with a Normal Distribution calculator – see link on this page).
Note that all the latest news is in this post – World Maths Day 2012.
John Page describes his ‘Math Open Reference‘ project as a free interactive textbook on the web, initially covering Geometry.
The tools include various function explorers. Younger students could explore linear functions for example, whilst older students could use the general Graphical Function Explorer to explore any functions, trigonometric for example.
