# #55: Coordinate Geometry

Coordinate Geometry is one of my favorite areas of math.  There’s just something about getting a sheet of order pairs and carefully plotting them on graph paper…connecting the dots to reveal a picture.  If that’s your sort of thing too, check out Option 3 below.  Happy plotting!

##### How can you spend your Math Minutes this week?
1. Learn the basics of coordinate geometry by watching this video (you have to scroll down the page a bit).  Read through the text underneath the video too.  Post a comment about something new you learned.  When leaving a comment, type your first name, grade level, and school (i.e. Trevor, 3, Sunset).  Do not type in your email address.
2. This video gives a musical explanation of the inventor of coordinate plane geometry, Rene Descartes.
3. Print out (or have your teacher print out) these worksheets.  Plot the ordered pairs on the graph paper and reveal a warm surprise!  Take a picture of your completed drawing and send it to the EY Coordinator at your building.
4. Hopscotch is a free programming app that utilizes coordinates plane geometry.  The video link below explains some basics of Hopscotch and another way to spend your Math Minutes this week.  NOTE: Due to app updates, the Hopscotch video may not match perfectly with the up-to-date-version of the app.  After watching the video, create your initials/name in Hopscotch.  Take a picture of your completed program and send it to the EY Coordinator at your building.  We would love to post it on our Student Showcase Wiki!

1. Jonathan W., 3, Sunset says:

I learned that coordinates can be used to draw and have fun, not just to say where you are. I also learned that y can go up to 700 in Hopscotch.

2. Lucas, 3, Sunset says:

I never knew that x and y meant up and down and that you could do many things using them to do those things on Hopscotch.

3. Lucas, 3, Sunset says:

I learned that you can use x and y to make different things on Hopscotch.

4. Eliot 6 Prairie says:

I watched the music video. It was funny and taught me about Descartes. Without him, we wouldn’t have technology(?)

1. lspady says:

What specifically did you learn about Descartes Eliot?

5. Noelle 4,paddock road says:

I learned that in hopscotch when you get a character and move it around the x and y coordinates are changing constantly

6. Andrew,4,Rockbrook. says:

I learned that X is first and Y is second!

7. Michael Z, Rockbrook says:

I like that x is first because it comes before y in the alphabet.
