# Ratios and Proportional Relationships Activites

## 6th Grade

6.RP.1

Intro to Ratios

Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

6.RP.2

Unit Rates and Unit Prices

Understand the concept of a unit rate a/b associated with a ratio a:b with b is not equal to 0, and use rate language in the context of a ratio relationship.

6.RP.3.a

Ratio Tables

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

Unit Rates and Unit Prices

Solve unit rate problems including those involving unit pricing and constant speed.

6.RP.3.c.i

Percent of a Quantity

Find the part of a whole, given the percent of a quantity.

6.RP.3.c.ii

Percent of a Quantity

Solve for the whole when given a part and the percent.

6.RP.3.d

Using Ratios to Convert Units

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

## 7th Grade

7.RP.1

Comparing Unit Rates

Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.

7.RP.2.a

Find, Show Proportional Amounts

Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

7.RP.2.b

Find, Show Proportional Amounts

Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

7.RP.2.c

Represent Proportions

Represent proportional relationships by equations.

7.RP.2.d

Represent Proportions

Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.

7.RP.3

Ratio, Proportion Word Problems

Use proportional relationships to solve multistep ratio and percent problems.
