General Lesson Information
 Lesson Plan ID: 33134 Title: You Sank My Coordinate Plane! (an introductory lesson in coordinate planes) Overview/Annotation: If you grab a bunch of jump ropes and tell your kids you're going outside, you can trick them into thinking they are getting recess. Instead, you can surprise them with a math lesson about how to identify the points on the coordinate plane! This is a College- and Career-Ready Standards showcase lesson plan.
Associated Standards and Objectives
Content Standard(s):

Local/National Standards:

Primary Learning Objective(s):

Students will be able to identify the four quadrants, point of origin, both the x and the y axis, and an (x,y) position on the coordinate plane--first on the playground, and then on paper.

Preparation Information
 Total Duration: 31 to 60 Minutes Materials and Resources: Graph Paper and Pencils/Pens--This is for when you finish up outside and come back into the classroom.Jump Ropes--You will need as many jump ropes as you can find, since you are creating a "life-sized" x and y axis, and the bigger you can make it, the more room your students will have, and the less likely they will become clumped together, unable to move. (I use eight 16-foot jump ropes, 4 ropes for each axis.)Whistle (recommeded, not required)--This is useful for corraling ten-year-olds who are super excited about doing a math activity instead of getting recess. Technology Resources Needed: Interactive whiteboard with a coordinate plane template (Otherwise, just spend a few extra minutes creating the biggest coordinate plane you can on your whiteboard, using different colors for the axis and for the points). Background/Preparation: Familiarity with a number line is very helpful, since the x axis is the untouched number line, and the y axis is the number line rotated 90 degrees counterclockwise.  And if your kids already know what the x and y axis are, they can set up the jumpropes for you!

Assessment
 Assessment Strategies In keeping with the introductory spirit of this lesson, a simple assessment is all that is required. So, in order to assess what they've learned, you should ask your students to do the following three things on their graph paper:1) Draw and label a coordinate plane (this includes the x and y axis--labled with x and y; this also includes the point of origin and all four quadrants labled correctly).2) Find and label the following four points on their coordinate plane: (4,4); (-4,4); (-4,-4);  (-4,4)3) Connect the four points with straight lines.The end result should be a square, making it easy for you to assess who needs extra help.
 Acceleration: After looking at the assessments, many students who are now fluent in the Primary Learning Objective will be anxious to create their own pictures using points on a coordinate plane. Have them do so, showing you a list of their points and a completed picture. If theirs is accurate, and if possible, post their points on your blog for other students in your class/school to try. Intervention: For the most basic remediation, I point to the tiles on my classroom floor, or the cinder blocks on the wall, and ask the students to identify numbers that I give them. For example, pointing at a floor tile (origin), I ask them to count four tiles from the origin, like they would on a number line. When they've gone four tiles to the right, I'll ask them to count two tiles up.  Repeated practice with the floor tiles (something with which they are very familiar) is a great place to start.Setting up yardsticks on the floor or a large piece of butcher paper to represent only quadrant one (all positive values for x and y) can help students who are still struggling. They can see the numbers on the yardstick--all positive numbers. Often, the concept of negative numbers is a sticking point, so focusing on the entirely positive quadrant on the coordinate plane will help students more easily understand how to use the coordinates to find a point. Also, this will very closely align with Content Standard 5-G2.
