Description
Use this Guided Notes document, in either Google Sheets online form or printable PDF, to help teach your students their second lesson in solving proportion problems. Proportion problems involve the relationship between two ratios. If the ratios are equal, then a proportion exists. In this lesson, the students will learn how to determine if two ratios really are equal. For example, consider these two ratios:
7/15 = 30/75
The way to determine that is with cross-multiplication. The numerator of the first ratio will be multiplied by the denominator of the second, and the numerator of the second ratio will be multiplied by the denominator of the first. 7 x 75 = 525. 15 x 30 = 450.
Since 525 does not equal 450 (525 ≠ 450), the ratios are not proportional or equivalent!
The Notes includes six practice problems. You can either let the students try solving them on their own, or lead them in one or more. After the students have finished this, have them do the online practice “Grade 6 Proportion Problems Check In 3”, “Grade 6 Proportion Problems Check In 4”, and/or worksheet “Grade 6 Proportion Problems Worksheet 2.”
You can save 30% by buying “Grade 6 Proportion Problems Lesson 2,” which includes all of these products.
After completing this lesson, your students will be ready for my “Grade 6 Percents Guided Notes 1” and its associated practice sets. Percents Guided Notes 1 shows students how to calculate percentages from ratios.
This worksheet relates to Common Core standard CCSS.MATH.CONTENT.6.RP.A.3 “Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.”
