Measuring the Carpet with Footsteps Case Study
Meena measures the floor carpet using her footsteps and counts 12 paces. Her brother counts 9 paces on the same carpet.
Analytical Task: Why is Meena's count 12 while her brother's is 9? Whose steps are bigger?
Evaluation & Model Answer:
1. Brother's steps are bigger (longer).
2. Because his steps are bigger, fewer steps (9) are needed to cover the carpet.
3. Meena's steps are smaller, so she needed 12 footsteps.
2. Because his steps are bigger, fewer steps (9) are needed to cover the carpet.
3. Meena's steps are smaller, so she needed 12 footsteps.
Rubric: 1.5 M for brother's steps are bigger + 1.5 M for fewer steps needed
