Week 10

(Module 2 Topic 2 Lesson 1 - 3: Multiplying and Dividing Rational Numbers)

Learning objective = Students divide integers and classify the quotients; they learn that the terminating and repeating decimal results are rational numbers. Students perform operations with positive and negative rational numbers as they calculate percent error and solve real world problems. actual value is less than the estimated value.

Parents can support learning at home by helping students connect this week’s lesson to real-life examples and practice explaining their thinking. Encourage your child to explain each step aloud rather than simply memorize a rule = SAMPLE TEST QUESTIONS + MORE QUESTIONS

***If your child needs more challenge, they can move at a faster pace by using this site to study the concepts of future lessons. Mr. Pierre will strive to prepare lessons two weeks ahead of the current week. Also, Khan Academy is a great enrichment resource***

Inventing Negative Numbers | Cyberchase | Grades 3-5, 6-8 Math K-5 Teaching and Lesson ResourcesIn this video segment from Cyberchase the CyberSquad is trying to rescue the Cyberspace Council, which is being held captive by Hacker in a tall building. As Motherboard provides information, the CyberSqaud uses a number line and their knowledge of negative numbers to locate the Council.

Solving Linear Equations with Negative Numbers | Grades 6-8 Math K-5 Teaching and Lesson ResourcesSolve a linear equation that has negative numbers and a variable. This video focuses on using inverse operations to solve for a variable. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.

Solving Linear Inequalities with Negative Numbers | Grades 6-8 Math K-5 Teaching and Lesson ResourcesSolve an inequality that has negative numbers and a variable. This video focuses on using inverse operations to solve for a variable and the importance of flipping the inequality when multiplying or dividing by a negative number. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.

Harry Makes a Big Splash with Positive and Negative Numbers | Cyberchase | Grades 3-5, 6-8 Math K-5 Teaching and Lesson ResourcesIn this Cyberchase video, Harry, his friend, and his cousin Harley form a swim relay team. They get timed in three different strokes to see who should swim which one in a relay. They look at the results and try to find the combination of times which will yield the lowest overall relay time. In the accompanying classroom activity, students pair up and play a game that gives them practice adding positive and negative numbers on a number line.
