  1. Properties Objective: Identify properties of addition and multiplication and use these properties to solve problems.

  2. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc

  3. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc 10

  4. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b

  5. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b 20

  6. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b

  7. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b 6

  8. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b)

  9. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) 20

  10. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) • (15ac)/(3c +6)

  11. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) • (15ac)/(3c +6) 12

  12. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) • (15ac)/(3c +6) • The number of fat Calories in a food item can be calculated by multiplying the number of fat grams by 9. • a. Write an expression for the relationship between fat grams and Calories.

  13. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) • (15ac)/(3c +6) • The number of fat Calories in a food item can be calculated by multiplying the number of fat grams by 9. • a. Write an expression for the relationship between fat grams and Calories. c = 9g

  14. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) • (15ac)/(3c +6) • The number of fat Calories in a food item can be calculated by multiplying the number of fat grams by 9. • a. Write an expression for the relationship between fat grams and Calories • b. Find the number of fat Calories in a bag of pretzels with 6 grams of fat.

  15. 5-Minute Check (lesson 1-3) • Evaluate each expression if a = 4, b = 2, and c = 3. • a + bc • 4a + b*b • ac/b • 7a – (2c + b) • (15ac)/(3c +6) • The number of fat Calories in a food item can be calculated by multiplying the number of fat grams by 9. • a.
