Math activity
Coordinate Treasure Hunt
Follow simple directions to find hidden treasure! Go 3 steps forward, turn right, go 2 steps forward. X marks the spot!
Materials and setup
- masking tape or chalk
- index cards
- small prizes or treats
- pencil
- paper
- tape measure
How this changes by age
Pre-K (ages 3–4)
Follow simple directions to find hidden treasure! Go 3 steps forward, turn right, go 2 steps forward. X marks the spot!
Steps
- Hide a small toy or treat somewhere in the room.
- Give directions: 'Take 3 big steps forward. Now turn right. Take 2 steps. Look down!'
- Practice following 3-4 step directions to find hidden objects.
- Use direction words: forward, backward, left, right, up, down.
- Now child hides something and gives YOU directions to find it!
- Tell a grown-up one thing that surprised you.
Learning objectives
- Follow multi-step directional instructions
- Use position and direction words: forward, backward, left, right
- Give clear directional instructions to another person
Kindergarten (ages 5–6)
Create a simple grid treasure map on the floor. Use coordinates like (Row 2, Column 3) to mark where the treasure is hidden.
Steps
- Use tape to create a 5x5 grid on the floor. Label rows 1-5 and columns A-E.
- Hide a treasure at one intersection. Write down the coordinate (e.g., Row 3, Column B).
- Give the coordinate clue to your child. Can they walk to the right spot?
- Hide 5 treasures at different coordinates. Give all 5 clues as a list.
- Child hides treasures and writes coordinates for parent to find.
- Tell a grown-up one thing that surprised you.
Learning objectives
- Navigate to positions on a simple grid using row and column labels
- Record positions using simple coordinate notation
- Create coordinate clues for others to follow
Early elementary (ages 6–8)
Use a coordinate plane to plan and run a treasure hunt. Plot clue locations as ordered pairs, calculate distances between clues, and decode the final treasure location.
Steps
- Create a coordinate grid from (0,0) to (10,10) on large paper or on the ground with chalk.
- Plot 6 clue locations as ordered pairs: Clue 1 at (2,3), Clue 2 at (7,1), etc.
- At each clue, hide a card with a math problem. The answer is part of the final treasure coordinate.
- Walk from clue to clue, solving problems and recording coordinate parts.
- Calculate the distance (in grid units) between consecutive clues.
- Solve all clues to discover the final treasure coordinate, then go find the treasure!
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Plot and locate points using ordered pairs in the first quadrant
- Calculate horizontal and vertical distances between coordinate points
- Apply coordinate skills to navigate a real-world treasure hunt
Upper elementary (ages 8–10)
Design a full coordinate plane treasure hunt using all four quadrants. Include clue solving with transformations, reflections, and distance calculations to find the treasure.
Steps
- Create a coordinate plane with all four quadrants (-10 to 10 on both axes) in your yard or on a large floor.
- Design 8 clue stations across all quadrants. Plot each on a master map.
- Clue types: (1) Reflect point (3,4) across the y-axis to find the next clue. (2) Translate point (-2,5) right 4 and down 3.
- Include a distance clue: 'The next clue is exactly 5 units from (1,2). It has a positive x and negative y. What point is it?'
- Use the Pythagorean theorem for diagonal distances: a clue at (0,0) and the next at (3,4). Distance = 5 units.
- Final challenge: all solved clues give coordinates. Plot them and connect to reveal the shape that tells where the treasure is hidden.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Navigate all four quadrants of the coordinate plane
- Apply transformations (reflections and translations) to find new coordinates
- Calculate distances using the Pythagorean theorem on a coordinate grid
Safety and evidence note
Read the full activity before beginning. An adult should supervise tools, heat, food, outdoor work, movement, and experiments as appropriate. Completion records that the activity was done; the child’s explanation, work sample, photo, or demonstration is stronger evidence of learning than a completion check alone.
