  1. Applying the Properties of Operations to Multiply and Divide Rational Numbers

  2. Evaluate the expression below: • −6×2×(−2)×(−5)×(−3)

  3. b. What types of strategies were used to evaluate the expressions? • c. Can you identify the benefits of choosing one strategy versus another? • d. What is the sign of the product and how was the sign determined?

  4. Find an efficient strategy to evaluate the expression and complete the necessary work. • −1×(−3)×10×(−2)×2

  5. What terms did you combine first and why?

  6. Discussion Question: Did the distributive property make this problem easier to evaluate? How so?

  7. Question: How is this expression different from the previous examples, and what can we do to make it more manageable?

  8. How do we determine the sign of expressions that include several products and quotients? • Name a property of operations, and describe how it is helpful when multiplying and dividing rational numbers.

  9. b. Give a value for 𝐴 that would result in a positive value for the expression. c. Give a value for 𝐴 that would result in a negative value for the expression.
