| |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. |
|numericalexpression coefficient |1. Make sense of problems and persevere in solving them. |
| associative property constant |2. Reason abstractly and quantitatively. |
|commutative property variable |3. Construct viable arguments and critique the reasoning of others. |
|distributive property |4. Model with mathematics. |
| |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. |
