# Coordinate graphing in Guided Math Groups

When I am introducing Coordinate Graphing, I read *A Fly on the Ceiling*. This is a great math fable about how Descartes came up with the Cartesian Coordinate graphing system. I also use these mathwire activities because they provide great scaffolding for the topic:

Here are some other resources:

I love coordinate grids! For the more tactile and physically inclined students (which most of my middle school students are) – we take all of the chairs and tables and move them out of the way. I draw a coordinate grid on the floor and away we go. I have done this with crayola markers but I prefer the permanent – cause it still comes off (unless of course you have carpet – then you can use masking tape – takes a lot longer) …

Then away you go … we talk about how to get to let’s say (4,5). I have one student go to that location. This way they get an idea of “how to get there” …

Once the students get a physical idea of the grid, I give them paper and we play “battleship” in teams.

anyway just a thought.
