How to Play
- Type a number between 0 and 100 or drag the slider to select the percent you want to model.
- Watch the pie chart shade the matching wedge while the 10 × 10 grid fills the same number of squares.
- Change the value repeatedly and describe what stays the same (total pieces) versus what changes (colored portion).
Knowledge Background
Percentages are fractions with a denominator of 100. Visualizing them as both circular sectors and grid squares helps students connect percents to fractions and decimals, paving the way for ratio/proportion work.
Why This Helps Kids
Linking multiple representations builds flexibility. Learners see that 75% can be three-fourths of a pie, 75 squares on the grid, or 0.75 on a number line. This depth is essential for interpreting charts, discounts, and probability later on.
Extensions & Teacher Tips
- Challenge students to estimate the shaded portion before revealing the exact value.
- Ask, “What fraction and decimal match this percent?” each time the slider stops.
- Connect to real-life scenarios: “If 60% of the class likes soccer, how many students is that?”
- Pair with Visualize Fractions or Match Fractions & Decimals for a complete equivalence study.
