Videos and lessons to help Grade 6 students learn to 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.

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

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.

D. Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.

Common Core: 6.RP.3b

- I can solve problems involving unit pricing and speed.
- I can find a percent of a given quantity involving finding the whole, given a part and the percent.

6.RP.3.b - Solve Unit Rate Problems with a Double Number Line Diagram (Singapore Math)

This video explains how to solve unit rate problems using a double number line diagram. This is a pictorial method for solving rate problems in the Singapore math curriculum when you are dealing with only 2 different units. This addresses 6.RP.3b in the Grade 6 Common Core Standards for Mathematics.
