  1. A dot at (2, 6) slides 1 square right. What is its new x-coordinate?

    Answer: ______________

  2. A dot is 3 squares along and 5 squares up. How do you write its position?

    • (5, 3)
    • (3, 3)
    • (3, 5)
    • (5, 5)

  3. A point on a grid is 3 across and 2 up from the corner. How do you write its coordinates?

    • (3, 2)
    • (2, 3)
    • (3, 3)

  4. In the coordinates (5, 1), the second number tells you how far up the point is.

    Circle one:   True   False

  5. A rectangle has corners at (1, 1), (5, 1), (5, 4) and (1, 4). What is its height (from bottom to top)?

    Answer: ______________

  6. A point is marked at (7, 2). How many squares across is it from the corner?

    Answer: ______________

  7. Which sentence about the point (4, 1) is correct?

    • 4 counts along and 1 counts up
    • 4 counts up and 1 counts along
    • Both numbers count along
    • Both numbers count up

  8. Ava reads (5, 3) as five along and three up. Is Ava right?

    Circle one:   True   False

  9. Leo says the point (2, 5) means 5 across and 2 up. Is he right?

    • Yes, that's correct
    • No, he swapped the numbers
    • No, the first number is always up

  1. 3 · The new x-coordinate is 3 because 2 + 1 = 3.
  2. (3, 5) · (3, 5) is correct because the along count comes first and the up count comes second.
  3. (3, 2) · The across number comes first, then the up number: (3, 2).
  4. True · That's right. The second number is always the vertical distance, how far up.
  5. 3 · The height is 3 because the top side is at 4 and the bottom side is at 1, and 4 - 1 = 3.
  6. 7 · The first number in the pair is the across distance, so it is 7 squares across.
  7. 4 counts along and 1 counts up · 4 counts along and 1 counts up is correct because the first number is horizontal and the second is vertical.
  8. True · Ava is right because she kept the along number first and the up number second.
  9. No, he swapped the numbers · The first number, 2, is across, and the second number, 5, is up. Leo swapped them.
  10. 7 · The new x-coordinate is 7 because 3 + 4 = 7.
