- Miscounted Grid Lines
- A student says that (3, 5) and (5, 3) are the same point because they use the same numbers. Is the student correct? Explain why or why not, and describe where each point is located on the coordinate plane.
- The kitchen map shows the walk-in cooler as a labeled point on the grid, with the pass counter at the origin. Which ordered pair names the cooler?
- (−4, 3)
- (−3, 4)
- (4, 3)
- (−4, −3)
- A server starts at the pass counter, the origin. She walks 7 units west, 4 units south, 3 units east and then 6 units north. West and south are the negative directions. In which quadrant does she stop?
- Quadrant I
- Quadrant II
- Quadrant III
- Quadrant IV
- The chef describes where each station is, starting from the pass counter at the origin. West and south are negative. Write the x- and y-coordinates, then the quadrant number (write 0 if the station is on an axis). Fill in every empty cell.
- Six kitchen stations are marked on the grid. A station that sits on an axis is not in any quadrant. How many of the stations are in Quadrant III?

InvestigateInvestiga
Use the model to test an idea. Then check it.
Usa el modelo para probar una idea. Luego compruébala.
- Where does each station sit? Sort every ordered pair by its location.
- Design a delivery route that starts at the origin. Choose three stops, with one stop on an axis. Write each stop as an ordered pair and tell how the courier gets there: first left or right, then up or down. Name the quadrant of each stop that is not on an axis.
- 4 fresh problems with new numbers each time (interactive only).

Somebody made a mistake. Find the step and fix it.
Alguien cometió un error. Encuentra el paso y corrígelo.
- Marco reads a point on the kitchen grid that is 4 units left of the y-axis and 3 units above the x-axis. Find the step where his work goes wrong.
- Nadia names the quadrant of the point (−5, 2). Find the step where her reasoning goes wrong.
- Omar says where the point (0, 5) is on the grid. Find the step where his reasoning goes wrong.
- A cook must put the fryer at (−3, 6). Ana walks 3 left and then 6 up. Ben walks 6 up and then 3 left. Cai walks 6 left and then 3 up. Who puts the fryer in the right place?
- Ana only
- Cai only
- Ana and Ben
- Ben and Cai
- What is the best next move?
- Write (4, 6), because distances are positive.
- Write (−4, −6): left is x, below is y.
- Write (−6, −4), putting the larger number first.
- Write (−4, 6), because only left is negative.
- 1 fresh problem with new numbers each time (interactive only).

- Which ordered pair is in Quadrant IV?
- (−4, 6)
- (−4, −6)
- (4, 6)
- (4, −6)
- A point has an x-coordinate of 0. Where can the point be?
- On the y-axis
- On the x-axis
- In Quadrant I
- In Quadrant II or IV
- Three stations are shown on the grid: P at (−2, 5), Q at (3, −4) and R at (−6, −3). Which station is in Quadrant IV?
- Station P
- Station R
- Station Q
- None of them
- The x-coordinate of a point is the opposite of 6, and its y-coordinate is the opposite of −2. In which quadrant is the point? Write the quadrant as a number from 1 to 4.
- A cook marks (−5, 4) for the fridge and (−5, −4) for the prep table. Which statement is true about the two points?
- They have the same y-coordinate, so they are on the same horizontal line.
- They have the same x-coordinate, so they are on the same vertical line.
- They are both in Quadrant II.
- They are the same point written two ways.
- Create your own kitchen map. Choose four stations, one in each quadrant, and write an ordered pair for each. Say how you know each quadrant, and describe how to walk from the origin to one of the stations.
