Week 14

(Module 2 Topic 1 Lesson 1 - 2: Ratios)

Learning objective = Students differentiate between additive and multiplicative reasoning in preparation for the study of ratios. They use the term ratio to identify a comparison between two quantities using multiplicative reasoning. They compare quantities using part-to-part and part-to-whole ratios written in words, colon notation, and fractional form. They identify fractions and percents as part-to-whole ratios.

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***

Human Tree: Ratios | Grades 6-8 Problems With Scale Drawings (Grade 7) Teaching and Lesson ResourcesWatch as the National Museum of Mathematics creates an interesting series of images using ratios. This video focuses on the proportional relationship observed in fractals and challenges you to do some critical thinking using ratios and scale factors. This video was submitted through the Innovation Math Challenge, a contest open to professional and nonprofessional producers.

Ratio and Ratio Language: Bianca Pigs Out | Cyberchase | Grades 3-5, 6-8 The Ratio Concept and Ratio Language (Grade 6) Teaching and Lesson ResourcesIn this video from Cyberchase, Bianca decides to make a stuffed animal for a baby. She encounters a problem when she needs to enlarge the pattern without using a photocopier but solves it by using a grid as a tool. In the accompanying classroom activity, students learn about ratio and proportion by enlarging their favorite comic strip with a grid.

Representing Ratios with Tables and Navigating a Table of Equivalent Ratios | Grades 6-8 Relating Quantities and Measurements With Ratio Tables (Grade 6) Teaching and Lesson ResourcesIn this video lesson, students encounter situations in which using a double number line poses challenges and for which a different representation would be helpful. Students learn to organize a set of equivalent ratios in a table, a more abstract but also a more flexible tool for solving problems. Students see that a table accommodates different ways of reasoning about equivalent ratios. They notice (MP8) that to determine an unknown quantity, they can find the multiplier or find an equivalent ratio with one quantity having a value of 1. Allowing students to use any representation that accurately represents a situation and encouraging them to compare different methods will develop their ability to make strategic choices about representations (MP5). The video lesson strengthens students’ understanding of the multiplicative relationships between equivalent ratios. It also builds students’ awareness of how a table can facilitate this reasoning to varying degrees of efficiency, depending on the approach.
