Today in Math we talked about how computer displays work on a coordinate grid system. Below is an image that shows how touchscreens use the same coordinate grid system to figure out where on the screen you are touching.
The entire touchscreen is laid out on a coordinate grid. Notice how in the last step that we get "exact coordinates." These are ordered pairs such as (3, 10) just like the ones we have been working with. If you'd like to read more from the site this image comes from,

Below is the video we watched on 3D printers. They plot points using the coordinate grid as well. Watch the movement of the printer head (the part that puts out the plastic material). It will be attached to two metal bars that allow it to travel in the x-axis and the y-axis.

Can you find other examples of how the coordinate grid is being used?
Very cool post! I'm a 4th grade teacher in Seattle and I'll be using this information in a PowerPoint for my students tomorrow! Thanks for sharing :)
