Today’s Agenda

In this lesson, students will learn about ratios and equivalent ratios. They will use tape diagrams and tables to represent ratios and determine if ratios are equivalent. The language objective is to use the four language domains to determine and use academic math language vocabulary.

  1. Today’s Agenda 10/7/16 ACTIVATOR: • Homework is out on the corner of your desk, • copy down tonight’s homework. • 3. Activator: Take out your math packet • and notebook. In your notebook put today’s • date in the corner, and Activator on the first line. • Copy and Answer: • For every 3 girls, there are 4 boys. There are 21 children in the class. How many boys are there? HINT: Make a table!!

  2. I will be able to use tape diagrams or the description of equivalent ratios to determine if two ratios are equivalent by using. • I will demonstrate my understanding by independently completing at least 4 levels correctly. 6.RP.A.1 6.RP.A.3

  3. Language Objective • By the end of the lesson, I will be able to use the four language domains of listening, speaking, reading and writing to determine and use the academic math language vocabulary of finding equivalent ratios. • I will use my understanding of equal ratios or equivalent ratios to find out if the ratios are equal. • I will show I understand by completing at least four levels correctly and independently.

  4. Ratios that have the same value Ex. 4:7 is equivalent to 12:21 Equivalent ratio

  5. Exercise 2Lets represent this ratio in a table. 3 7 14 6 21 9 We use a tape diagram to represent the ratio of the lengths of ribbon. Let’s create one. 

  6. Tape Diagram (Bar Model)

  7. Equivalent Ratio!

  8. Page 13: EXAMPLE 1 You would have to know the total number of 6th graders, and then see if the ratio 24 :total is equivalent to 2:7 The value that makes the ratios equivalent is 12

  9. How do you feel? topic.

  10. I can use my class examples to help • Everyone independently start on LEVEL half sheet you left off on. • When done, come see a teacher. • If correct, teacher will ask to move to the next level. • Our goal, complete at least 4 of the level worksheets.

  11. How do you feel? topic.

  12. Exit Ticket: (on sticky note) There are 35 boys in the sixth grade. The number of girls in the sixth grade is 42. Lonnie says that means the ratio of the number of boys in the sixth grade to the number of girls in the sixth grade is 5:7. Is Lonnie correct? Show why or why not. HOMEWORK pg. 14

  13. Accommodations • Read or reread presentation or activity directions, as needed or after prompting • Use examples to model and act as a guide for emerging learners
