Section 1
The Meaning of Percent
Property
A percent is a ratio that compares a number to 100.
The symbol % means "per hundred," so any percent can be written as a fraction with a denominator of 100.
In this Grade 6 lesson from Reveal Math, Course 1 (Module 2: Fractions, Decimals, and Percents), students learn to understand percent as a rate per 100 and express it using ratio notation such as 45:100 or 45/100. Students practice identifying and modeling percents using two visual tools: 10×10 grids, where each square represents 1%, and bar diagrams divided into equal sections representing multiples of 5% or 10%.

Section 2
Modeling Percents with 10x10 Grids
A 10x10 grid contains exactly 100 equal squares, making it an ideal model for percents. The entire grid represents the whole, or , and each individual square represents .
