Success criteria
- I read and write ordered pairs as
(x, y). - I move across the x-axis before moving up the y-axis.
- I use coordinates—not visual guessing—to answer a map question.
Learn and explain
An ordered pair is written (x, y): move across first, then up. The library is at (2, 3). Explain how (2, 3) differs from (3, 2).
Independent practice
Which ordered pair locates the Garden?
Read x first: 6 across, then 7 up.
The Library and Court share y = 3. How many grid units apart are they?
units
Their horizontal distance is |8 − 2| = 6 units.
Unfamiliar transfer — route change
A meeting point starts at (3, 2) and moves 4 units right and 5 units up. Plot both points on paper and draw arrows before answering.
Where is the new meeting point?
The translated point is (7, 7).
Delayed check
One week later, ask someone to name four first-quadrant points. Plot them, label them, and write one comparison using “same x,” “same y,” or “farther.”
Evidence path
Save the paper route map to jeremy/portfolio/math/unit-5/lesson-14-coordinates/.
Next step
- Repair: cover the labels and rehearse “across, then up.”
- Continue: if plotting and interpreting are independent, classify shapes.
- Stretch: four quadrants unlock only after the Unit 5 core gate, not from this lesson alone.
