Rope Rescue
Estimate, Cut, and Save the Day!
Don't look down! Rope Rescue is a high-stakes investigation into the vertical number line. Designed for Key Stage 2, students must estimate exactly where to cut a rope to lower a climber safely to a ledge.
Cut it too short, and they stay stranded. Cut it too long... well, let's just say gravity takes over. It covers Fractions, Decimals, and Percentages within a vertical context.
🧗 How to Play
- Receive the Intel: The mission briefing tells you where the ledge is (e.g., "Cut at 50%" or "Cut at 3/4").
- Scan the Rope: The rope represents a number line from 0 (top) to 1 (bottom) or 0 to 100.
- Estimate: Visualise where 50% (halfway) is. Glide your mouse/finger to that spot.
- Cut!: Click to snip the rope. Watch the climber rappel down. If they land on the safety pad, mission accomplished!
📚 Curriculum Focus (KS2)
Rope Rescue targets "Number - Fractions (including decimals and percentages)":
- Estimation Estimate the position of fractions and decimals on a number line.
- Equivalence Understand that 50%, 0.5, and 1/2 are the same position on the rope.
- Visualising Scale Grasping that 10% is near the top and 90% is near the bottom.
🧠 Vertical Number Lines
Most classroom number lines are horizontal. However, real-world gauges (thermometers, sea level, elevators) are vertical.
Rope Rescue helps students generalise their understanding of lines and scale to a vertical format, strengthening their overall "Number Sense."
👨👩👧 Tips for Parents
The "Petrol Gauge" Game:
- Look at a liquid jug or fuel gauge. "It's half full. Is that 50%?"
- "Where would 25% be? Show me with your finger."
- "If we drink half of this half... what fraction is left?" (1/4 or 25%).
