Product Description
Seven stations include practice or review finding the slope and the y-intercept of linear functions from two given points, from graphs and from tables of values.

Students work in groups of three, labeling themselves Student A, Student B and Student C. Each student works their own problem at a station in their own notebook. Students then add their three answers together for the “Sum”. They check the back of the station/page to see if the “Sum” of their answers is correct before moving to the next station. Students may rotate through the stations in any order.

CCSS: Use functions to model relationships between quantities.
8.F.B.4 Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
CCSS: Interpret linear models.
HSS.ID.C.7 Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
CCSS: Build a function that models a relationship between two quantities.
HSF.BF.A.1 Write a function that describes a relationship between two quantities.
CCSS: Construct and compare linear, quadratic, and exponential models and solve problems.
HSF.LE.A.2 Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).
CCSS: Create equations that describe numbers or relationships.
HSA.CED.A.2 Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
HSA.CED.A.4 Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.
CCSS: Interpret functions that arise in applications in terms of the context.
HSF.IF.B.6 Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.

Teacher Setup:
Print each page on card stock or paper. Write only the numerical “Sum” of the three answers on the back of the corresponding page for students to check. Attach the pages to the walls around the room as stations for the students to visit.

Included in the package:
• Seven “Sum It Up” pages/stations, each with three problems, to put on walls around the classroom
• “Sum” answers to write on the back of each page/station for students to use
• Detailed answer key for the teacher

This activity works well in the middle of a lesson when students are actively learning a new skill and can also be used as a review.

The instructions are clearly marked on the students’ page and the answer key is included.
