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.
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., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
Similar to the above listing, the resources below are aligned to related standards in the Common Core For Mathematics that together support the following learning outcome:
Understand ratio concepts and use ratio reasoning to solve problems
