2. Ms. Owens visited New York City last year and took a taxi to see a Broadway show. The taxi charged a $2 pick up fee and $3 per mile. It was 12 miles from the hotel to the theater. Write a numerical expression that would help to answer, then evaluate.

3. 2 + 3 x 12 3 x 12 + 2 Discuss in your team why both expressions gave you the same value.

4. A student in last year’s class wrote this expression to find the cost of the taxi: (2 + 3) ● 12 In your teams, discuss whether this expression is also equivalent to 2 + 3 x 12 and 3 x 12 + 2. Be prepared to mathematically justify.

5. Using (2 + 3) ● 12, create a real life situation that the value of this numerical expression could match.

6. Day 2 Review: On your dry erase board, translate the following numerical expression into words. **Be sure not to use the “outlawed” words from yesterday! ( 3 X 4) + 18 Challenge: Can you give a real life situation to match this expression?

7. Now let’s practice placing parentheses. After each expression, think about a real life situation that might match.

8. 1.Place the parentheses in the correct place to make the expression equal 12.

9. 2. Place the parentheses in the correct place to make the expression equal 12.

10. 3. Place the parentheses in the correct place to make the expression equal 12.

11. 4. Place the parentheses in the correct place to make the expression equal 12.

12. 5. Place the parentheses in the correct place to make the expression equal 12.

13. 6. Place the parentheses in the correct place to make the expression equal 12.

14. 7. Place the parentheses in the correct place to make the expression equal 12.

15. Exit Ticket: 6 + 2 ● 3 Place parentheses to make this numerical expression equal 24. Then write a real life situation to match.
