The learning connection
A 100-grid makes percentage literally visible as parts of a hundred — the clearest possible representation of what percent means. Students who shade grids before calculating percentages develop proportion intuition that formula-only students almost never build.
Try it with your learner
1. Get grid. 2. Shade 25 squares yellow. 3. Write 25%. 4. Shade 50 more. 5. Find total.
