- 7.RP.A.1Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction (1/2)/(1/4) miles per hour, equivalently 2 miles per hour.
- 7.RP.A.2Recognize and represent proportional relationships between quantities.
- 7.RP.A.3Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.

Proportional Reasoning and Percent - Can you apply the concepts? (3 Day Lesson)

7th Grade Math

Â» Unit:

Percents

Big Idea:What's the point of learning it if you can't apply it in the real world? Students will apply concepts learned in the RP strand of the common core to real world problems.

Scaling a Recipe

7th Grade Math

Â» Unit:

Proportional Relationships

Big Idea:In this task, students scale recipes up so that there is enough for seconds and thirds!

pHun with Phenolphthalein

7th Grade Science

Â» Unit:

Cells: Structure, Function, and Processes

Big Idea:The origin makes all the difference in this relationship.

Proportional and Nonproportional Relationships - Can you find the constant?

7th Grade Math

Â» Unit:

Proportional Reasoning

Big Idea:You have heard of moving at a constant speed or doing something at a constant rate - but did you know that was a proportional relationship?

Proportional Reasoning Test - Time to Put it All Together!

7th Grade Math

Â» Unit:

Proportional Reasoning

Big Idea:Time to test! Let the students show you what they have learned about proportional relationships!

7.RP.A.2a

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.A.2b

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

7.RP.A.2c

Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.

7.RP.A.2d

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.
