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.
Differentiation — Support
Provide a printed coordinate-plane anchor chart with quadrant labels and sign rules (I = +,+; II = −,+; III = −,−; IV = +,−).
Allow students to use a number line to reason about positive/negative direction before plotting.
Pair struggling students with a peer for Steps 1–3; transition to independent work for the quiz.
Accept verbal explanation of distance in lieu of written for students with writing supports.
Differentiation — Challenge
Ask students to plot a polygon with a given perimeter, then justify their vertex choices.
Have students reflect a rectangle across both axes and describe the transformation in writing.
Extend Q5 (self-check): ask what would happen to the distance if one endpoint moved to (6, 10).
ESOL / Language Supports
Preview vocabulary in L1 if available: ordered pair, quadrant, axis, origin, reflect.
Use sentence frames: "The point (__, __) is in Quadrant __ because x is __ and y is __."
Allow students to label the axes in their home language on scratch paper.
Visuals: the coordinate plane diagram in the 3D game doubles as a visual glossary; direct students to the game before the quiz.
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.
Name and plot points like (−3, 4) in all four quadrants.
Find which quadrant a point is in by its signs.
Reflect a point across an axis and describe how the sign changes.
Plot the corners of a shape and find a side length by counting units or using absolute value.
Pass the Self-Check (5 items) and complete a written reflection.
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
Learn the words. The x-axis goes left and right. The y-axis goes up and down. They cross at the origin (0, 0).
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 (−).
Know the quadrants.
Quadrant I = (+, +) · II = (−, +) · III = (−, −) · IV = (+, −).
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.
Play the 3D game below to plot stars and practice.
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.
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.
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: 5 Quick Questions
Answer each question, then press Check This Answer to see instant feedback.
Teacher Answer Key (Self-Check)
Q1: B — The x-coordinate tells horizontal position.
Q2: B — (−5, 3) is Quadrant II (negative x, positive y).
Q3: B — (−4, −7); reflecting across y-axis negates x only.
Q4: 8 — |−2| + |6| = 2 + 6 = 8 units.
Q5: A — 4 units; |5 − 1| = 4.

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.
