When starting “Volume” with Year 8, we start by looking at cubic units and isometric drawings. This year, with an interactive whiteboard (although, these resources are also suited for use with just a projector or in a computer lab), I was able to use a couple of excellent online resources.
Are you drawing mathematical diagrams in Microsoft Word? You might even be achieving success doing this; once you’ve worked out how to wrangle Microsoft apps to do what you want, they can be powerful. But, for drawing mathematical diagrams there are better options.
FX Draw by Efofex is the application for drawing static diagrams for inclusion in worksheets, assessment tasks etc. The one down-side of this software is that there is no Mac version. (The rest of the Efofex MathPack is worth the money as well)
I was preparing for part of a presentation to the staff at my school tomorrow, highlighting the importance of numeracy being included in all subject areas.
Term 3 will see the roll-out of netbooks to Year 9 at my school (some photos of the Lenovo S10e).

Here’s a PowerPoint file I made to quickly review transformations before getting into congruency.
