Solving systems of linear equations can be very confusing for Algebra students. This learning progression covers graphing, the substitution method, and elimination method to solving systems of linear equations. It corresponds to two Common Core State Standards they are CCSS.Math.Content.HSA.REI.C.5 and CCSS.Math.Content.HSA.REI.C.6. The learning progression includes assessments that can be used to evaluate the students’ progress in achieving the standards. Throughout the learning progression, different learning environments are used to help a diverse set of students. Whole class discussion, individual, and group work are used to help students build thoughts and ideas and still be responsible for their own learning.
Here is the learning progression and a lesson plan:
