📚 Part 1: Are They Equivalent?

I Can: Identify when two expressions are equivalent by comparing their values.

1. Circle YES if the expressions are equivalent, or NO if they are not equivalent.

a) 5 + 3 and 8

YES

b) 4 + 2 and 7

YES

c) 3 × 2 and 6

YES

2. When x = 4, which expressions are equivalent to 7? Check all that apply.

x + 3

x + 4

3 + x

x - 1

✏️ Part 2: Substitution Practice

Success Criteria: I can substitute values for variables and determine if expressions are equivalent.

3. If x = 5, find the value of each expression. Then circle YES or NO if they are equivalent.

Expression 1: x + 2 = _____ + 2 = _____

Expression 2: 2 + x = 2 + _____ = _____

Are these expressions equivalent?

YES

4. Test if x + 1 and 1 + x are equivalent when x = 3.

My conclusion: These expressions are _________________ because _________________________________.

5. Real-world problem: Maria buys 3 pencils for $2 each. Which expressions show how much she spent?

3 × 2

2 + 2 + 2

3 + 2

🎯 Part 3: Create Your Own

6. Write two different expressions that are both equivalent to 10.

Expression 1: ________________________

Expression 2: ________________________

7. Extension Challenge: Create a real-world situation where x + 4 and 4 + x would both describe the same amount.

8. Explain in your own words: What does it mean for two expressions to be equivalent?
