Note: The mini-lesson above has audio. It gives a brief introduction to the concept of percent and illustrates the importance of the number 100 in all percentage calculations. It is the first in a series of three mini-lessons. Select from the options below to view the other two mini-lessons on calculating with percent.

Lesson #1

The Percentages Lesson explained above is aligned with the standard 6RP03 from the Common Core Standards For Mathematics (see the shortened extract below). The resources below are also aligned to this standard.

*Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., ...*

- Customizable Percentage Chart - You enter the values!

- Converting Between Ounces and Grams (0g - 1000g plus blank scaled lines)

- Calculating Percentage Values e.g. 62% of 12 = 7.44
- Calculating Percentage Values e.g. 225% of 45 = 101.25
- Decimals to Percent e.g. .45 = 45%
- Fractions to Percent e.g. 7/100 = 7%
- Calculating using Percentage Values e.g. 72 is 25% of 288
- Simplifying Ratios (1 of 2) e.g. 4:2 = 2:1 (includes prompts to divide by G.C.F)
- Simplifying Ratios (2 of 2) e.g. identify and simplify ratios
- Comparing Fractions (4 of 4) - ordering fractions, decimals, and percentages
- Fractions, Decimals, & Percentages (1 of 2) - fill in equivalents chart
- Fractions, Decimals, & Percentages (2 of 2) - fill in equivalents chart
