# Copy of 2. Identify and describe ratio relationships (MELD)

Lesson objective: Represent a situation using a ratio, in multiple different ways.

This lesson has been  revised from its original format to include modifications for teaching English learners (ELs). The original lesson is located at: https://learnzillion.com/lesson_plans/2553-2-identify-and-describe-ratio-relationships-fp.

This lesson helps to build fluency with writing ratio statements.  The distinction between part-to-part and part-to-whole relationships is used here because it supports students' development of the multiple ways to represent the same situation. This work develops students' understanding that a ratio is a comparison by division.

Students engage in Mathematical Practice 4 (model with mathematics) as they apply ratio reasoning to a real life situation.

Key vocabulary:

• ratio
• colon
• part
• whole
• part to part ratio
• part to whole ratio
