| |Unit 2.3: Proportional Reasoning with Rates | |
|Grade Level: 7th grade |Essential questions: |Suggested Days: 10 |
| |• What is a ratio? How do you recognize a ratio in a real-world or mathematical situation? | |
| |• How do you recognize a unit rate? What information does it provide? | |
| |• When given a ratio, such as a ratio of fractions, describe at least two different strategies you could | |
| |use to find the unit rate. | |
| |• How many different unit rates can be written for a given ratio? What does each unit rate mean? Give an | |
| |example to explain your response. | |
| |• How can you label the quantities in the problem to clarify your process and the | |
| |meaning of your answer? | |
| |• Why does division make sense in this situation? | |
| |• Why is the quotient of two positive fractions larger than the dividend? Use a model or | |
| |drawing to justify why your answer makes sense. | |
| |• Given a unit rate in a problem situation, how can you determine equivalent rates? | |
|Vocabulary: | |
|Ratios |Mathematical Practices: Highlighted practices to be assessed. |
|Fractions |1. Make sense of problems and persevere in solving them. |
|Complex fractions |2. Reason abstractly and quantitatively. |
|Unit Rates |3. Construct viable arguments and critique the reasoning of others. |
|Equivalency |4. Model with mathematics. |
|Proportions |5. Use appropriate tools strategically. |
| |6. Attend to precision. |
| |7. Look for and make use of structure. |
| |8. Look for and express regularity in repeated reasoning. |
