2. Topic 1.1
The Cartesian Plane

3. Cartesian Plane – The plane formed when a horizontal number line and a vertical number line cross. Also called a coordinate grid.

4. 4 3 2 1 -4 -3 -2 -1 1 2 3 4 -1 -2 -3 -4

5. X – axis – The Horizontal Line on the number grid.
Y – axis – The vertical number line on the coordinate grid. 2 1 -2 -1 1 2 -1 -2

6. Origin – The point where the x-axis and y-axis cross.
Quadrants – The four regions on the coordinate grid. 2 1 -2 -1 1 2 -1 -2

7. 4 3 2 1 -4 -3 -2 -1 1 2 3 4 -1 -2 -3 -4

8. Quadrant II Quadrant I Quadrant III Quadrant IV 4 3 2 1 -4 -3 -2 -1 14
Quadrant II
Quadrant I 3 2 1 -4 -3 -2 -1 1 2 3 4 -1
Quadrant III
Quadrant IV -2 -3 -4

9. Coordinates – The values in an ordered pair.
Ordered Pair – (x, y)
Examples:

10. Quadrant II ( - , + ) Quadrant I ( + , + ) Quadrant III ( - , - )4
Quadrant II
( - , + )
Quadrant I
( + , + ) 3 2 1 -4 -3 -2 -1 1 2 3 4 -1
Quadrant III
( - , - )
Quadrant IV
( + , - ) -2 -3 -4

12. Battle Ship
In grade pairs gr 7/gr 8 at your table, you will each color 3 ships onto your playing grid.
The ships must each cross over at least 3 coordinates.
Once player pair up, one player must guess coordinates on their partners Cartesian Plane, to try and ‘Sink their Battle Ship’

13. Cartesian Plane Examples (Please Follow Along & Write These Down)
Identify points on a coordinate grid.

14. Cartesian Plane Examples (Please Follow Along & Write These Down)
Plot the following points on a coordinate grid:
A(-4,3), B(-2, -1),
C(5, 3), D(4, -1),
E(-5, -2)

15. Textbook Questions
In pairs work through the following textbook questions:
Note: Pairs must have one grade 7 student & one grade 8 students
Math Links 7 – Page 8
#’s – 2, 5, 7, 9, 13
When you’re done, you may play Battleship

16. Learning Log Response
What are the similarities and differences between two points with coordinates (0,3) and (3,0)?
