WALT (We Are Learning To):

• Identify coordinates and plot points on all four quadrants of the Cartesian plane
• Read and describe locations using ordered pairs (x, y)
• Navigate and describe movements using directional and coordinate language

---

Success Criteria:

Students will be successful if they can:

✅ Accurately plot points on the Cartesian plane
✅ Read and record coordinates using ordered pairs
✅ Correctly describe positions and direction using mathematical language (e.g., up/down, left/right, quadrants)
✅ Complete tasks independently or with guided support
✅ Demonstrate spatial reasoning through hands-on mapping work

---

Materials Required:

• Large laminated Cartesian plane mat for floor activity (4x4 quadrant layout)
• Mini whiteboards & markers
• Individual printed grid sheets (Cartesian plane with four quadrants)
• Pre-made coordinate cards (points to plot)
• Rulers and coloured pencils
• Laptops/iPads (if available for digital extension task)
• Classroom visual poster showing quadrants and example coordinates
• ‘Cartesian Coordinates Challenge’ worksheet (early finisher task)

---

LESSON STRUCTURE (60 Minutes)

---

✅ 5 Minutes — Daily Review (On the Mat)

• Students gather on the mat.
• Teacher asks: “Who can remind us what we learned last Maths lesson?”
• Review previous learning on grids, directional language (left, right, up, down), and reading simple coordinates in the first quadrant.
• Confirm understanding before moving deeper into plotting on the full plane.

---

🧠 20 Minutes — Explicit Teaching (Whole Class)

1. Introducing the Cartesian Plane (5 minutes):

   • Display a large Cartesian grid (with quadrants I–IV) on the board.
   • Briefly introduce origin (0,0), x-axis (horizontal), and y-axis (vertical).
   • Define terms: axis, quadrants, coordinates, ordered pair.

2. Modelling (10 minutes):

   • Use magnetic coordinate points or plot points live on large grid on whiteboard.
   • Teacher models identifying and plotting coordinates: (3,2), (-2,4), (-3,-3), (4,-1) etc.
   • Describe what each pair means using language like “3 across, 2 up”.

3. Interactive Example (5 minutes):

   • Students stand around the floor grid mat.
   • Teacher calls a coordinate (“Go to point (-2,3)”), and selects a student to walk to correct position.
   • Ask peers to check and explain the movement.
   • Use a few turns to build engagement and understanding.

✏️ 25 Minutes — Independent Practice

Main Task: Cartesian Treasure Map

• Students are given a grid sheet titled “Pirate’s Treasure Map” with pre-drawn obstacles (trees, rocks, volcano island etc.).
• Students must plot given coordinates correctly to find 5 hidden treasure spots marked as red X’s.
• Then, they write coordinate clues for a peer to find the treasure on a blank copy of the map.

Teacher Role During Independent Time:

• Sit with weaker students (see Support Group task below).
• Check for basic misconceptions (e.g., axis confusion, positive vs negative directions).

---

👥 Differentiation

🛠️ Support Students

• Work in a small group with the teacher.
• Use a simplified coordinate grid (first quadrant only or with colour-coded axis).
• Start by plotting only positive coordinates, then gradually introduce negative values.
• Teacher uses physical movement ("stand at the origin, now walk 3 steps left and 2 steps down") before using paper-based tasks.

Modified task:

• “Find the Dragon” — Students plot simple positive coordinate points to create a shape of a dragon tail and trace it out.

🌟 Early Finishers / Extension Task

• Extension Worksheet: ‘Cartesian Coordinates Challenge’
  Includes:

  • Plotting complex figures (e.g., shape of a house or spaceship)
  • Creating their own coordinate picture using 10−12 points and writing the list of coordinates for a friend to copy and plot
  • Bonus logic puzzle: Use a list of directional instructions (e.g., “Start at (1,1). Move 2 left and 3 up…”) to find the treasure

• Technology Extension (if available):
  Students use a geometry/drawing app like GeoGebra or Google Jamboard to recreate their coordinate pictures digitally.

---

🔁 10 Minutes — Review and Conclusion (On the Mat)

• Gather students back to the mat.
• Discussion: “Who'd like to share where their treasure was hidden today? What was the coordinate?”
• Ask a few students to explain how to find a point in Quadrant III or IV.
• Use ‘Think-Pair-Share’: What happens if the x or y value is 0?
• Consolidate using a game-style exit ticket: Call out coordinates rapid-fire – students give thumbs up/down or stand/sit if it’s in a certain quadrant (e.g., stand if it's in Quadrant I).

---

Assessment Opportunities:

• Observation of student responses during mat time and questioning
• Exit ticket and reflection discussion
• Completed “Treasure Map” worksheets, showcasing plotting accuracy and reasoning
• Notes (anecdotal) on support group progress with coordinate identification and movement

---

Teacher Reflection (Post-lesson):

• Note which students are confidently using all four quadrants
• Identify those still requiring support with directionality or axis naming
• Adjust future lessons to include follow-up activities using real-world mapping, such as city grids or navigating digital mazes

---

Future Learning:

• Apply knowledge of coordinates into transformations: translations, reflections
• Explore coordinate applications in digital technologies (graphing, coding)
• Integrate mapping with Geography: latitude/longitude systems comparing real-world mapping to Cartesian planes
