Eight stations include practice or review solving multi-step linear equations using inverse operations. The activity includes problems involving addition, subtraction, multiplication and division.
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: Solve equations and inequalities in one variable.
8.EE.C.7 Solve linear equations in one variable.
8.EE.C.7b Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
HSA.REI.B.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
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.
