🎯 WALT: We Are Learning To plot and read coordinates on the Cartesian plane

Success Criteria:

• I can identify the four quadrants
• I can plot positive and negative coordinates accurately
• I can read coordinates from plotted points

Part 1: Drawing and Identifying (8 marks)

1. Draw a Cartesian plane with x and y axes from -5 to +5. Label both axes and mark the origin.

2. Label the four quadrants as I, II, III, and IV on your Cartesian plane above. (2 marks)

3. Which quadrant contains points with:

a) Positive x and positive y coordinates: Quadrant _____

b) Negative x and positive y coordinates: Quadrant _____

c) Negative x and negative y coordinates: Quadrant _____

d) Positive x and negative y coordinates: Quadrant _____

Part 2: Plotting Coordinates (10 marks)

4. Plot these points on your Cartesian plane above and label each point:

A (3, 2) B (-4, 1) C (-2, -3) D (0, -4) E (4, -2)

5. Multiple Choice: The point (-3, 4) is located in which quadrant?

Quadrant I

Quadrant II

Quadrant III

Quadrant IV

6. What are the coordinates of a point that is:

a) 3 units right and 2 units down from the origin? ( ____ , ____ )

b) 4 units left and 5 units up from the origin? ( ____ , ____ )

Part 3: Reading Coordinates & Extension (7 marks)

7. Write the coordinates of these points plotted on your plane:

Point A: ( ____ , ____ ) Point B: ( ____ , ____ ) Point C: ( ____ , ____ )

8. Extension Challenge: If you move point A (3, 2) five units to the left and three units down, what are the new coordinates?

9. Problem Solving: A treasure map shows that treasure is buried at coordinates that are in Quadrant III, where both coordinates are the same number. Give two possible locations:

Location 1: ( ____ , ____ ) Location 2: ( ____ , ____ )

10. Explain in your own words what the origin (0, 0) represents on the Cartesian plane:
