Eight stations include practice or review solving systems of linear equations using the graphing method, the substitution method and the linear combinations or elimination method.
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: Analyze and solve pairs of simultaneous linear equations.
8.EE.C.8 Analyze and solve pairs of simultaneous linear equations.
8.EE.C.8a Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.
8.EE.C.8b Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection.
8.EE.C.8c Solve real-world and mathematical problems leading to two linear equations in two variables.
CCSS: Solve systems of equations.
HSA.REI.C.5 Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.
HSA.REI.C.6 Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
CCSS: Create equations that describe numbers or relationships.
HSA.CED.A.3 Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context.
Print each page on cardstock 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:
• Eight “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 or as a review.
The instructions are clearly marked on the students’ page and the answer key is included.
