Chart the Star Map: The Coordinate Plane

Grade 6 Math · Standards 6.NS.C.6 & 6.G.A.3

Learning Target

I can…

  • Name and plot ordered pairs (x, y) in all four quadrants of the coordinate plane.
  • Identify which quadrant a point belongs to by the signs of its coordinates.
  • Reflect a point across an axis and explain the change in sign.
  • Find the distance between two points that share an x- or y-coordinate by counting units or using absolute value.
  • Plot the vertices of a polygon on the coordinate plane and find a side length.
Standards: 6.NS.C.6 & 6.G.A.3 Estimated time: 45–60 min Materials: grid paper, pencil, ruler (optional)

Pacing

This WebQuest is designed for one 45–60 minute class period. Suggested breakdown: Introduction + Task (5 min) → Process Steps 1–3 (15 min) → 3D game (10 min) → Shape activity + Self-Check (15 min) → Reflection (5 min). The NTKit check can be assigned as homework if time is short.

Grouping Suggestions

Pairs work well for Steps 1–3 (discuss quadrant rules together). The 3D game can be played individually or in pairs sharing a screen. The Self-Check quiz should be completed independently for grading purposes.

Introduction

You are a space navigator. Each star sits at an ordered pair like (x, y) on a star map. The map is a coordinate plane with four parts called quadrants. Your job is to read points, plot points, and draw shapes so your ship can reach every star.

Key words: x-axis (left/right) · y-axis (up/down) · origin (0, 0) · ordered pair (x, y) · quadrant (one of four regions)

Your Task

By the end you will:

Deliverable Complete all process steps, pass the Self-Check with at least 4/5, write your reflection, then press Check My Answers in the NTKit panel and save as PDF or DOC to turn in.

Process — Follow the Steps

  1. Learn the words. The x-axis goes left and right. The y-axis goes up and down. They cross at the origin (0, 0).
  2. Read a point. In (x, y), the first number is x (left/right). The second number is y (up/down). Right and up are positive (+). Left and down are negative (−).
  3. Know the quadrants. Quadrant I = (+, +) · II = (−, +) · III = (−, −) · IV = (+, −).
  4. Understand reflections. Reflecting a point across the y-axis flips the sign of x. Example: (3, −2) becomes (−3, −2). Reflecting across the x-axis flips the sign of y.
  5. Play the 3D game below to plot stars and practice.
  6. Draw a shape. Plot 4 corners on grid paper. To find a side length when two points share a y-value, add their distances from 0 (absolute values). Example: (−2, 5) to (6, 5) → |−2| + |6| = 2 + 6 = 8 units.
  7. Complete the Self-Check below. Check each answer, read the feedback, then use the NTKit form to save your work.
Tip: To find the distance between two points on the same row or column, subtract the smaller absolute value from the larger, or add if they are on opposite sides of zero.

Evaluation — Rubric

Skill 4 — Expert 3 — Proficient 2 — Developing 1 — Beginning
Name & plot ordered pairs All points correct in every quadrant; explains the x-then-y rule. Most points correct; minor counting errors only. Some points correct; consistently confuses x and y. Needs significant support to plot any point.
Identify quadrants by signs Always uses signs correctly; can explain why without the diagram. Usually correct; rare sign mix-up. Mixes up some quadrants, especially II and IV. Cannot yet use signs to locate a quadrant.
Reflections across axes Reflects correctly across both axes; explains the sign change. Reflects correctly across one axis; minor errors on the other. Understands direction of reflection but sign error present. Reflection concept not yet demonstrated.
Distance / side lengths Uses absolute value correctly; exact answer every time. Counts units correctly; occasional small slip. Needs help setting up the count; some answers correct. Cannot yet find the distance between points.
Self-Check score 5/5 correct 4/5 correct 2–3/5 correct 0–1/5 correct

Self-Check: 5 Quick Questions

Answer each question, then press Check This Answer to see instant feedback.

1. In the point (x, y), what does the first number (x) tell you?
2. Which point is in Quadrant II (−, +)?
3. Point P is at (4, −7). It is reflected across the y-axis. What are the new coordinates?
4. Point A is at (−2, 5). Point B is at (6, 5). How many units long is segment AB? (Type a whole number.)
5. A rectangle has corners at (1, 2), (5, 2), (5, −3), and (1, −3). What is its width (horizontal side length)?
Teacher Answer Key (Self-Check)
  1. Q1: B — The x-coordinate tells horizontal position.
  2. Q2: B — (−5, 3) is Quadrant II (negative x, positive y).
  3. Q3: B — (−4, −7); reflecting across y-axis negates x only.
  4. Q4: 8 — |−2| + |6| = 2 + 6 = 8 units.
  5. Q5: A — 4 units; |5 − 1| = 4.

Check Your Understanding (for Grading)

Type your name in the panel, answer the 6 grading questions, then press Check My Answers and save as PDF or DOC.

1. In the point (x, y), what does the first number tell you?
2. Which point is in Quadrant II (−, +)?
3. The point (0, 0) is called the —
4. Type the ordered pair that is 3 left and 4 down from the origin. (Use this form: −3,−4)
5. Point A is at (−2, 5). Point B is at (6, 5). How many units long is segment AB? (Type a number.)
6. Which quadrant holds points where BOTH numbers are negative (−, −)?

Conclusion

Great work, navigator! You can now read and plot ordered pairs, name quadrants by their signs, reflect points across axes, and use the grid to find side lengths. These coordinate-plane skills help with maps, graphs, and geometry all year.

Student Reflection

Answer both questions in your own words. Write in complete sentences.

1. Which part of the coordinate plane was hardest for you today, and how did you figure it out?

2. Give one real-world example where someone would need to use an ordered pair or a coordinate plane.
