## Chapter 1: Ratios and Rates

## Standards

- 6.RP.1 - Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.
- 6.RP.2 - Understand the concept of a unit rate associated with a ratio, and use rate language in the context of a ratio relationship.
- 6.RP.3 - Use ratio and rate reasoning to solve real-world and mathematical problems.
- 6.RP.3a - Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
- 6.RP.3b - Solve unit rate problems including those involving unit pricing and constant speed.
- 6.RP.3c - Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, given a part and the percent.
- 6.RP.3d - Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
- 6.NS.4 - Find the greatest common factor (GCF) of two whole numbers less than or equal to 100 and the least common multiple (LCM) of two whole numbers less than or equal to 12.
