Discussion points for teachers

1. Explain how the reflection would be different if it was reflected in the x or the y-axis.
Discuss which is the x and the y-axis. How can you remember which is which? How would the reflections be different?
If the ship was reflected in the x-axis then it would move into the bottom right quadrant and vertex A would be at the bottom of the shape. If the ship was reflected in the y-axis then it would move into the top left quadrant and vertex A would remain at the top of the shape.

2. Draw the ship’s new position and write the new coordinates.
Discuss strategies for reflecting: tracing paper, mirrors. Discuss and model how both techniques can be used. Discuss writing the letters of the vertices on the tracing paper to keep track of each point.
A = (3, -4) ; B = ( 2, -3) ; C = (4, -3) ; D = (2, -1) ; E = (4, -1)

3. On your coordinate grid, draw the new position of the ship and write the coordinates of each vertex .
Discuss the difference between translating and reflecting. Discuss how you are keeping track of the ship’s position.
A = (-2, -4) ; B = ( -3, -3) ; C = ( -1, -3) ; D = ( -3, -1) ; E = (-1, -1)

4. Explain Pearl’s mistake.
Discuss what mistakes are easy to make when reflecting. Discuss top tips for making accurate reflections.
Pearl has used translation rather than reflection. After the reflection in the y-axis, the vertex she has given is vertex C.

5. What are the coordinates of the ship?
Discuss which of the shapes on your coordinate grid shows the actual position of the ship.
A = (2, -4) ; B = (3, -3) ; C = (1, -3) ; D = (3, -1) ; E = (1, -1)
