Week 30

(Module 4 Topic 1 Lesson 1: Signed Numbers)

Learning objective = Students use the structure of a number line to make sense of negative numbers. They plot rational numbers and their opposites on a number line. Students investigate how the meaning of zero in a situation affects the placement of points on a number line. They compare rational numbers in the context of temperatures and profits/losses.

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***

Additive Inverse | Grades 6-8 p + q as Distance |q| from p (Grade 7) Teaching and Lesson ResourcesThis animated Math Shorts video from the Utah Education Network explains the term additive inverse and provides several examples that demonstrate the concept. In the accompanying classroom activity, students create equations and solve problems that involve adding groups of negative and positive integers that sum to zero. To get the most out of this activity, students should be familiar with plotting positive and negative integers on a number line.

I <3 Math: Integers | Grades 3-5, 6-8 Quantities With Positive and Negative Numbers (Grade 6) Teaching and Lesson ResourcesExploring positive and negative integers and how we use them in the real world. This I <3 Math episode explains the difference between positive and negative numbers and how these numbers can be represented on a number line.

Comparing Positive and Negative Numbers, Part 1 | Grades 6-8 Inequalities and Relative Positions on Number Line Diagrams (Grade 6) Teaching and Lesson ResourcesUsing temperature, students compare rational numbers and learn to write inequality statements that include negative numbers. Students then consider rational numbers in all forms (fractions, decimals) and compare them by plotting on a number line and considering their relative positions. Students abstract from “hotter” and “colder” to “greater” and “less,” so if a number a is to the right of a number b, inequality statements a > b and b < a can be written. Students also find that the greatest number is not always the one farthest from zero. For example, -100 is much farther away from zero than -1/100, but since -1/100 is to the right of -100, it is larger and can be written -1/100 > -100. Students are briefly introduced to the word sign (i.e., algebraic sign) since it is often used to talk about whether numbers are positive or negative. Students use the structure of the number line to reason about relationships between numbers (MP7). Grade 6, Episode 20: Unit 7, Lesson 3 | Illustrative Math

Introduction to Negative Numbers | Cyberchase | Grades 3-5, 6-8 Quantities With Positive and Negative Numbers (Grade 6) Teaching and Lesson ResourcesStudents are introduced to the concept of negative numbers through simple equations and the use of a number line that is extended beyond zero in the negative (left) direction.

Harry Makes a Big Splash with Positive and Negative Numbers | Cyberchase | Grades 3-5, 6-8 Division Fluency Using the Standard Algorithm (Grade 6) 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.
