There’s actually a lot more to coordinates than is perhaps given space for in a lot of schemes of work.
I certainly have been guilty of skipping over the topic before, on the basis that the kids can ‘do it’ and have made trouble for myself later on down the line.
It’s not just about ‘along the corridor and up the stairs’. There’s the idea that a coordinate represents a position and is made up of an x and a y value.
I’ve tried to get a this here, but I slightly worry that I’ve mixed in too many ideas.
I’ve also hinted at straight line graphs and sequences with some mini-whiteboard work.
I’ve also talked about the MOVEMENT of coordinates.
Manipulating coordinates and being comfortable doing so is, I think, important.
Hopefully this is packed with a lot more thinking that what I used to do early on in my career. Print off a sheet of some coordinates and ask students to read some and plot some. There’s nothing wrong with that kind of thing, but I’m not sure it should be the main event.
Similarly, I tried to make my plotting work a bit more involved.
The coordinate geometry slides are mainly about finding the midpoint.
But I did something I don’t normally do. I copied in the late, great Don Steward’s Quadrilaterals and Coordinates slides. Normally I write all my own questions, but these are BEAUTIFUL questions, and every classroom is richer for doing them.
I had no way to add or improve on these.
If you are a member of Don’s family, and would like these slides removed, please contact me.
That’s all for now.
I just need to do some slides on Pictograms, and then the entire of MathsGenie’s grade 1 content is covered by TickTockMaths slides. I’m pretty proud of that, and hope to get to full coverage of up to grade 2 by the end of the year.
