Module 8: Exploring Algorithms
Module Objectives In this module you will: a) Solve a task involving scientific notation and Order of Operations b) Explore algorithms related to subtraction, multiplication, and division. |

Task 1: Distances in SpaceThe table below gives you the average distance of 3 planets from the Sun. |
||
Mercury 5.7x10^{7 } km |
Venus 1.08 x10^{8 } km |
Earth 1.5x10^{8 } km |
How far are each of those planets from the Sun in million kilometers? How far are each of those planets from the Sun in thousand kilometers? Susan said, "Venus is more than twice as far from the Sun than Mercury is." Tyrone said, "Earth is more than twice as from the Sun than Mercury is? Are they correct? Why or why not? Scientific notation is used to express large numbers in terms of powers of ten. The Grade 5 Common Core Standards ask students to: How does the work that you did above with the distances between the planets relate to each of these Standards? Submit your work in a Word document. |

Task 2: Algorithms and Strategies Here is an article on how place value understanding influences students' use of algorithms. Read the article. Here are the figures that go with it. Here is work on multiplication strategies. Complete the attached task. Here is some information on division strategies. Here are more strategies. Use three of the division strategies described to solve the task: 444 divided by 16. As you were solving these tasks using various strategies, how did your understanding of place value and number sense help you? Submit your work in the same Word document as Task 1. |

Task 3: Final Project Go back to the previous module for directions. This is due August 6. |

Work due at the end of this module: Task 1- Final project- submit through Moodle2 or e-mail |
