Here is a little freebie poster that I've just done up to show the little saying that was taught to me by one of the kids in my class when I taught Grade 6 to remember to read the x-axis before the y-axis (wow, that was a long sentence!).
It is simple: You crawl before you walk! When you crawl you are horizontal so you read the horizontal axis first, you are vertical when you walk so you read that second. I thought it was pretty genius and I've been using it ever since! I'm pretty sure he learned it from a previous teacher, so thank you if it was you!
Click on the pic to download. I've done two up: one with letters and one with numbers along the x-axis.
Edit: I often receive emails asking if I know of other Aussie blogs. Well, if you are an Aussie, or even if you're not, I've created a page that has links to other Aussie blogs. Click on the link under the blog header if you want to check out some Aussie talent!
