The Linear Systems Unit + Activities Bundle (Unit 3) includes notes, practice, reviews, assessments, PLUS activities.
Documents are in PDF format. Editable versions of all forms of the mid-unit assessment and test are also included in DOCX (MS Word) format.
The Linear Systems Unit (Unit 3) covers formulating and solving systems of linear equations consisting of 3 linear equations in 3 variables. It builds off of students’ experience solving 2x2 systems of linear equation in Algebra 1. The unit also extends students’ Algebra 1 knowledge of graphing systems consisting of 2 linear inequalities in 2 variables to formulating and solving 2-variable systems of inequalities containing two or more linear inequalities. Non-linear systems consisting of one linear equation and one quadratic equation will be addressed in a subsequent unit during the study of quadratic functions.
This versatile unit addresses multiple strategies for solving 3x3 systems of linear equations, including lessons on substitution, elimination, Gaussian elimination, inverse matrices, and augmented matrices.
Students do not need any prior knowledge of matrices to be successful in this unit. Flexible assignments are designed to accommodate adjustments to sequencing.
Students also will formulate, graph, and solve 2-variable systems of linear inequalities (2+ inequalities). Students will identify possible solutions to systems of linear inequalities. Additionally, they will extend their study of systems of inequalities to linear programming applications.
Two forms (A/B) are included for added versatility in your classroom. In-context keys are included for easy grading. Plus plenty of opportunities for students to engage with the process standards.

Primary Standards Addressed
2A.3A. 2A.3B, 2A.3E, 2A.3F, 2A.3G from Texas Essential Knowledge and Skills (TEKS)
A note from Allison at Math Beach Solutions about standards alignment: This resource was designed from the ground up to provide ready-made resources for Texas teachers to implement to facilitate their students’ mastery of the Algebra 2 TEKS (Texas Essential Knowledge and Skills TAC §111.40). A considerable effort has been made to ensure the TEKS are addressed thoroughly, but these resources will reflect my understanding of the TEKS. As always, continue to use your professional judgement and experience when lesson planning.
