### Four Quadrant Coordinate Graphing

We have spent this school year graphing in Quadrant 1 only.  I wanted to have a little fun and give the kids a challenge, so I introduced them to the other three quadrants.

Coordinate graphing is based on plotting points using two coordinates (ie.  3,6).  The first coordinate tells where to move along the x-axis, and the second coordinate tells where to move along the y-axis.  Up to this point my students have only worked with positive coordinates.  This means they have only worked in Quadrant 1 (+,+).  We began by taking notes and working with a small picture to practice our new knowledge.

The four quadrants are as follows:

• Quadrant 1 (+, +) or right and up
• Quadrant 2 (-, +) or left and up
• Quadrant 3 (-, -) or left and down
• Quadrant 4 (+, -) or right and down
To see how this was explained, please watch:  Four Quadrant Coordinate Graphing.

Once we had a little practice.... I posed the challenge.... complete the Mystery Picture.  This is NOT homework for tonight!  They have all week to work on it as time allows.  I would like it turned in on Friday.

Remember.... Math STAAR test is tomorrow!
