Learning Goal
Part of: Understand ratio concepts and use ratio reasoning to solve problems — 1 of 3 cluster items
Understand the concept of a ratio
**6.RP.A.1**: Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak." "For every vote candidate A received, candidate C received nearly three votes."

What you'll learn
- Define a ratio as a relationship that describes how two quantities are related to each other, and distinguish this from a single number or measurement
- Use ratio language - "for every," "for each," "to," "per" - to describe a ratio relationship between two quantities in context
- Write ratios in all three standard notations: a to b, a:b, and a/b, and move fluently between them
- Identify whether a ratio describes a part-to-part relationship or a part-to-whole relationship, and explain the difference
- Recognize that a ratio is not the same as a fraction, even though they share notation - a ratio compares two separate quantities, while a fraction names a single value representing part of a whole
