Day 1: Introducing the Coordinate Plane
Objectives:
1- To learn the components of the coordinate plane.
2- To plot a point on the coordinate plane.
3- To construct a scatter plot and use data from a Ôreal worldÕ application.
1- To help students learn various components of the coordinate plane. I would begin by asking my students if any of them already knew anything about the coordinate plane and ask them to share. This allows for students to link new knowledge with knowledge they already have. I would also have the students get out a blank piece of graphing paper and draw a coordinate plane on it, describing what each line represents. As each of the new components is learned, they will be able to label these on their pages. New topics that will be discussed are:
a. Origin points (0,0)
b. X- and y-axis
c. 4 quadrants
i. Q1= x, y are both positive
ii. Q2= x is negative, y is positive
iii. Q3= x, y are both negative
iv. Q4= x is positive, y is negative
I would have my own coordinate plane on a transparency in the front so the students can see exactly what I am explaining.
2- To teach students how to plot points on the coordinate plane, the first thing to teach is ordered pairs.
a. X-value first, then the y-value
b. Have kids plot a few points on their planes and make sure everyone understands.
c. Give the students a set of 9 points, 2 from each quadrant and the origin.
d.
3- Applications
a. I will give the students a set of data that represents something from the real world.
b. Ask them to make a grid, plot the points
c. Explain to them that they just made a scatter plot. And explain what a scatter plot is.
d. Ask them to answer previously made up questions from their scatter plot.
