It's coming to the end of year madness. Matrics are almost finished and it feels like everyone else in the school wants to join in their silliness. We're tired, the learners are tired, and now we must teach an imaginative piece of content with excitement?
If only it were easy. If only someone else could give us ideas...
Robyn gave us unusual examples to use in class. Most of them did not make use of cards, dice or coins. (I can hear your sigh of relief from here!) We're all so bored with those examples. At the end of the day, probability is about far more than gambling. Ask any Maths Lit teacher and they'll tell you about the contexts they use.
In last week's show with Tamlyn, we spoke about the need to make everything meaningful. It's just as important to make everything meaningful in this section. Stop using stale examples. Stop teaching the methods without understanding. Start by introducing the need to compare probabilities, then show them how to calculate probabilities. Always emphasize that probabilities can be expressed in fractions, decimals and percentages.
Let's take a look at Robyn's presentation.
I said I would re-post all of the links from Robyn's last show. Here they are:
- A list of ideas for data collection.
- A comparison of the mass of animal's brains versus their bodies.
- Probability problems.
- A website explaining and summarizing mean and standard deviation with worked examples.
- A video explaining standard deviation and mean.
- A video explaining normal distribution and standard deviation.
- A webpage explaining normal distribution, bell curve and standard deviation. Easy to follow and worked examples.

I got completely confused about intersection and union. Robyn tried to explain it to me, but without the visual representation, I was lost. Here is a YouTube clip that explains them really simply though.
And remember, if you are struggling with any other content knowledge, take a look at the Mindset website.
Well, that's it for now folks. Until next time, happy teaching!
