| |Unit 1.3: Understanding Expressions and Equations | |

|Grade Level: 7th grade |Essential questions: |Suggested Days: 10 |

| |How can you clearly state the meaning (including the units) of the variables? | |

| |What mathematics does this expression represent? What real-world situation might this expression | |

| |describe? | |

| |How are equations and expressions different? (e.g., An equation states that two expressions are | |

| |equivalent.) | |

| |When can you combine (or separate) terms in an expression? | |

| |How many different ways can you rewrite 5x? | |

| |How can you factor an expression? When is factoring an expression useful? | |

|Vocabulary: | |

|algebraic expression         term                  |Mathematical Practices: Highlighted practices to be assessed. |

| |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. |

|coefficients. |Wed-based activities, videos, and powerpoints |journals, peer/self assessments, think-pair-share, quizzes |

|7.EE.2 Understand that rewriting an expression in different forms | |Post test (summative) |

|the same as “multiply by 1.05.” | (7.EE.1) |linear expressions containing rational numbers. |

| | |• Use properties of operations to factor and |

| | |rational numbers. |
