Order of operations web

  1. 1. Bell Ringer You buy a used guitar for $50. You then pay $10 for each of five guitar lessons. Write an expression for the problem. Find the total cost.
  2. 2. Bell Ringer You buy a used guitar for $50. You then pay $10 for each of five guitar lessons. Write an expression for the problem. (10 x 5) + 50 Find the total cost. $100
  3. 3. Where we were… • Commutative Property of addition • Order doesn’t matter in addition • 5 + 1 = 1 + 5 • Associative Property of addition • Grouping numbers in different ways doesn’t change the sum • (1 + 2) + 3 = 1 + (2 + 3) • Identity Property of addition • Adding 0 to any number doesn’t change the number • 14 + 0 = 14
  4. 4. Where we are… • Students will learn to… • Review Order of Operations • Define and combine terms
  5. 5. Vocabulary • Terms • Parts of an expression that are added together. • Why do you think the definition mentions only adding and not subtraction? • Order of Operations • a set of rules used to evaluate expressions with multiple terms
  6. 6. 5 + 6 x 5 • The goal for order of operations is to simplify the expression so that only addition (or subtraction) is left. • Which operations should I do first? Why? • 5 + 6 x 5 • 5 + 30 • 35
  7. 7. 10 x 3 + 32 • Which operations are most complex? • Which operations need to be completed in order to leave only addition? • 10 x 3 + 32 • 30 + 9 • 39
  8. 8. 20 – 42 ÷ 2 • Which operations are most complex? • Which comes first? Exponent or division? • You can’t use the quantity of 42 until it is simplified. • 20 – 16 ÷ 2 • 20 – 8 • 12
  9. 9. 18 – 10 + 5 - 1 • Which is the most complex operation? • They subtraction and addition are equally complex… subtraction can be changed to addition • Work left to right… • 18 – 10 + 5 • 8 + 5 - 1 • 13 – 1 • 12
  10. 10. Order of Operations 1) Evaluate expressions inside grouping symbols 2) Evaluate powers 3) Multiply and/or divide from left to right 4) Add and/or subtract from left to right
  11. 11. Homework • Pg. 19 • #1-2, 6, 8, 15-16, 43 • 7 Problems • Tell me your book # • Due on Friday
  12. 12. Where we were… • Properties of addition • Commutative Property • Associative Property • Identity Property • Addition and Subtraction of Integers • Adding the opposite can change all subtraction problems to addition. • Order of operations
  13. 13. Where we are… • Students will learn to… • Study the distributive property • Describe how the distributive property works
  14. 14. Partner Activity • Read the article • Alternate paragraphs with your partner • On a separate sheet of paper, answer the questions in the magazine. • Once you are finished, come get a worksheet • Answer the questions with your partner • Staple your paper and worksheet together and hand it in before you leave.
  15. 15.
