  12. Monday, Nov 18 Lesson 6.1 Powers and Exponents

  13. Powers and Exponents Objective: To understand how to represent numbers using exponents.

  14. Powers and Exponents At the end of this lesson you should be able to answer the following question. How is using exponents helpful?

  15. Powers and Exponents Fitness Fortress recycles plastic water bottles. On Saturday, 8 bottles were placed in the bins. On Sunday, 8 bottles were recycled.

  16. Powers and Exponents You can use bar diagrams to represent the number of bottles recycled. Use a second bar to represent the number of bottles recycled on Sunday.

  17. Powers and Exponents You can use bar diagrams to represent the number of bottles recycled. Use a second bar to represent the number of bottles recycled on Sunday. Saturday Sunday 8 bottles 8 bottles

  18. Powers and Exponents We can also write this as an addition expression. How many terms are in the expression? 8 + 8 = Saturday Sunday 8 bottles 8 bottles

  19. Powers and Exponents We can also write this as an addition expression. How many terms are in the expression? 2 8 + 8 = Saturday Sunday 8 bottles 8 bottles

  20. Powers and Exponents We can also write this as an addition expression. Would the answer represent a sum, product or quotient? 8 + 8 = Saturday Sunday 8 bottles 8 bottles

  21. Powers and Exponents We can also write this as an addition expression. Would the answer represent a sum, product or quotient? Sum 8 + 8 = Saturday Sunday 8 bottles 8 bottles

  22. Powers and Exponents We can also write this as an multiplication expression. Would the answer represent a sum, product or quotient? 2 x 8 = Saturday Sunday 8 bottles 8 bottles

  23. Powers and Exponents We can also write this as an multiplication expression. Would the answer represent a sum, product or quotient? Product 2 x 8 = Saturday Sunday 8 bottles 8 bottles

  24. Powers and Exponents Some expressions can be written as the product of a sum. For example, 2 x (1 + 4). The expression 2 x (1 + 4) can be thought of as having two factors, 2 and (1 + 4).

  25. Powers and Exponents The expression 2 x (1 + 4) can be thought of as having two factors, 2 and (1 + 4). Which factor is a sum?

  26. Powers and Exponents The expression 2 x (1 + 4) can be thought of as having two factors, 2 and (1 + 4). Which factor is a sum? 1 + 4

  27. Powers and Exponents Using a bar diagram 2 x (1 + 4) can be written as follows. 1 4 4 1

  28. Powers and Exponents Complete questions 7- 21 on pages 431-432 with a partner. You have 15 minutes. Reminders-factors are something you multiply to get a product.
