Using Coordinates
Objective (Teaching Point):
Find a point on a grid
Read and Plot Coordinates
Solve a problem to work out a missing coordinate
Lesson:
Projected coordinate graph on the board. Review the 4 quadrants and the positive and negative values on the axes.
Remember: when plotting or locating a point on a graph its value on the x-axis goes first then the y-axis (x,y).
Students will be asked to locate points being read out loud by the teacher and find missing points to complete shapes. ex/ plot the points for example: (-2, 4), (8, 0), (-3, -2), (0, -9).
Challenge: write the coordinates of the vertices of a triangle with area of 12 units square.

Extension:
1) The ice cream store wants to locate their new shop halfway between Riverside and Fairview. Riverside is located at (2,4) on the grid shown below. Greenville is located at (12,4).
Where should the shop be located?
2) Aidan is participating in an 8 mile walk for his favorite charity. The organizers used a coordinate grid to plot the course. The starting point is at (3,1) and the ending point is at (3,9). At (3,7), there's a water station to make sure the walkers stay hydrated.
Plot the starting point, ending point, and the water station.
How far along will Aidan be in the walk when he reaches the water station?
3) Maya is putting up one of her paintings in her living room. Suppose there were a grid on the wall where each unit measured a foot. The painting is represented by the inner square and the frame is represented by the outer square. Maya places a nail so that it lies halfway across the top of the frame.
On the graph, plot the point where Maya places the nail.
Name the point by filling in the blanks.
4) A map of the local disc golf course shows the holes on a grid similar to the coordinate plane. The tee on the first hole is at the point (1,2), and the hole is at the point (8,2).
Plot the two points representing the tee and the hole.
Find the distance between them.
5) Ying is putting up one of her paintings in her living room. Suppose there were a grid on the wall where each unit measured a foot. The upper-left corner of the frame is at the point (1,8) and the upper-right corner at (7,8). The bottom-left corner is at (1,2) and the bottom-right corner at (7,2).
Plot the four corners of the frame.
What is the width of the painting plus frame?
Conclusion:
On a coordinate grid plot the points (2,10), (-4, -2).
