Teaching Grade 10 Euclidean Geometry

9/9/2014

This is now the fourth webinar we've done on Euclidean Geometry and with every person, I see a little more of how fun and interesting the section can be.

Dylan came out from behind the buttons to tell us about one of his favourite sections, Euclidean Geometry. It was quite obvious to see his passion.

In the preparation conversations, Dylan kept emphasizing the importance of developing key skills. These are reason, generalise, conjecture, investigate, justify, prove and explain. All of these skills help with developing sound arguments, whether in Maths or other subjects, or even in future life.

We kept referring to previous conversations we'd had with Leigh. If you'd like to watch those again, go here for Grade 11 and here for Grade 12. We've also spoken to Jacques about teaching Grade 10.

Let's take a look at the information on Dylan's main slides.

3 Pressure Points:

You either got it or you ain’t
Problem solving skills take time to bake
Geometry is not algorithmic

5 Point Teaching Strategy:

Get all the basics in place (triangles and quads)
Work with theorems intuitively (measure, explore, discover, generalise)
Apply theorems to numeric problems
Apply theorems to abstract problems
Prove theorem formally

Good Ideas:

Geometry Toolbox
Group work
Slow burn
Make your own ryders

Here are some links that will help:

Here are some cheat sheets you could use to help you:

I feel like I've just skimmed the surface of what we spoke about. In order to get real value out of this, you should take the time to watch the webinar. The last half of it was dedicated to the differences between numeric and abstract problems and strategies to teach both.

Well, that's it for now. Until next time, happy teaching!
