Product Description
RATIOS AND PROPORTIONAL RELATIONSHIPS MIDDLE SCHOOL MATH STATIONS

...........................................................................................................................

• 7th Grade Common Core Math Standards from 7.RP.A.1, 7.RP.A.2.A, 7.RP.A.2.B, 7.RP.A.2.C, and 7.RP.A.2.D.

• Analyze proportional relationships and use them to solve real-world and mathematical problems.

CCSS.MATH.CONTENT.7.RP.A.1
• Compute 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.

CCSS.MATH.CONTENT.7.RP.A.2
• Recognize and represent proportional relationships between quantities.

CCSS.MATH.CONTENT.7.RP.A.2.A
• 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.

CCSS.MATH.CONTENT.7.RP.A.2.B
• Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

CCSS.MATH.CONTENT.7.RP.A.2.C
• 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.

CCSS.MATH.CONTENT.7.RP.A.2.D
• 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.
20 stations total; 2 stations per page; 1 problem per card

HOW CAN YOU USE THIS ACTIVITY?

• Cut out and laminate stations so you can use them every class period and every year!

• I typically have students work in partners, but BOTH of them have to fill out the student information sheet, showing work. Students could also work individually. Working with more than one person gets too crowded, and some students skate by without participating at all.

• Each group will start at a station. They will be given a certain amount of time to complete each task. At the end of the time, they will switch to the next station. Example: If a student starts at station 1, they will go to station 2. If they are at station 20, they will go to station 1.

• There should never be more than two people at a station (unless you have more than 40 students…).

• Encourage (or require) students to write down EVERY problem so that if they run out of time on one station, they can finish earlier problems at another station.

• Give students a specific time to complete each task. (1-2 min) Use a timer that goes off to help students know when to switch stations. This way, when the timer goes off, students will just get up and move without direction. Determine the amount of time based on the skill set of each group. I give some classes more time than others if needed. If I start with 2 minutes and all of the students are finishing quickly, I will decrease the time as we go. Usually 2 minutes is too much!

• I use this resource every year in the middle school math classroom. It can take up to a whole class period depending how much time is given to the students per station.
