"There are 12 boys and 14 girls in Mrs. Smith's class. Represent the ratio of girls to boys in 3 different ways."
The student will represent a ratio written in 3 different forms.
2 Independent Practice
Monitor student completion of Khan Academy activity.
Students will watch 2 lesson videos on ratios and proportions on Khan Academy. After completion of the videos, students will take a "quiz" and record their score with the teacher.
Administer review quiz for students.
Complete the kahoot review with groups.
Key Standards Supported
Ratios And Proportional Relationships
|6.RP: Understand Ratio Concepts And Use Ratio Reasoning To Solve Problems.|
|6.RP.1||Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.” “For every vote candidate A received, candidate C received nearly three votes.”|
|6.RP.2||Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. For example, “This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar.” “We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger.”1|
|6.RP.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.|
|6.RP.3.a||Make tables of equivalent ratios relating quantities with whole- number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.|
|6.RP.3.b||Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?|
|6.RP.3.c||Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.|
|6.RP.3.d||Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.|
