MathsClass

In the past, Maths teaching resources amounted to printed materials (be it a textbook, BLM). If the teacher didn't like what was available to them, they could hand-draw and Gestetner a more appropriate worksheet.

I wrote about my t-shirt box back in 2009. It’s a resource I still use in my classroom. When teaching surface area I have peel off sides for the box which can be placed on the board to show the net.

I like teaching surface area, I think it’s an interesting topic. Yet, I find kids struggle with the concept. Not understanding the basics of area and then getting over the prior knowledge of solids meaning volume are two aspects that cause some difficulty.

I’m about to get into Surface Area with Year 8. Of course, there will be chocolate. But, since I last looked at Surface Area with Year 9 I’ve been thinking about Heat Sinks.

An excuse to use chocolate in a maths lesson…

Google Sketchup is one of the applications bundled on the DER netbooks being rolled out into NSW Public High Schools in Term 3. But as it’s free, you can download it now for Windows XP/Vista & Mac OS X.
