Description

Get a complete, ready-to-print unit covering topics from the Algebra 2 TEKS including 3-variable systems of equations and systems of linear inequalities.

Substitution, elimination, Gaussian elimination, inverse matrices, augmented matrices, and linear programming are among the topics included in this unit.

UNIT OVERVIEW:

The study of linear systems in Algebra 2 extends students' prior knowledge about writing and solving two-variable systems of equations and expands on those foundational concepts to introduce writing and solving 3-variable systems of linear equations.

Students will solve 3x3 systems of linear equations using substitution, elimination, Gaussian elimination, inverse matrices, and augmented matrices. Teachers may opt to teach only the methods that are best suited to their students and course.

Students also will formulate and graph systems of linear inequalities, including applying their knowledge of linear inequalities to linear programming situations.

These no-prep resources include 8 lessons with guided notes, an exit ticket, a next-day warm-up, and 2 extra practice assignments per lesson.  The unit also includes mid-unit and end-of-unit reviews, mid-unit and end-of-unit editable assessments, and concept organizers. Increase student engagement with 10 TEKS-aligned activities! Increase student engagement with 10 TEKS-aligned activities!

_______________________________________

TEACHERS LOVE the worked-out keys included with the lessons notes. Feel confident delivering instruction on these sometimes tricky topics! It is a major time-saver if you don’t have quite enough time to create your own guided notes key for the day.

STUDENTS LOVE the reduced note-taking burden with the guided notes handouts. Fill-in-the-blank vocabulary improves the accuracy of students’ notes and frees up more time for showing mathematical steps. 

TEACHERS LOVE the multiple versions of each practice worksheet, review, and assessment and they take full advantage of the EDITABLE versions of the mid-unit assessment form and unit test.

STUDENTS LOVE the complementary concept organizers that help them organize concepts and procedures.  

TEACHERS LOVE the pre-made exit tickets and next-day warm-ups that support skills from every lesson in the unit. Print 4-per-page or project on the board and record answers on scratch paper.

STUDENTS LOVE the variety of fun and engaging activities!  

______________________________________

Most resources are in non-editable PDF format.

  • Editable versions of the mid-unit assessment and test are also included in .docx format for MS Word.
  • 5 digital activities compatible with Google Slides and Google Classroom™ are included. (Printable versions of the digital activities are included in PDF format.)

Lesson 3: 3x3 Elimination

Students will:

  • solve three-variable systems of linear equations algebraically using elimination (combination)
  • solve systems resulting in no solution and infinitely many solutions

Lesson 4: Gaussian Elimination

Students will:

  • use Gaussian elimination to solve three-variable systems of linear equations

Lesson 5: Inverse Matrices

Students will:

  • solve three-variable systems of linear equations using inverse matrices and technology
  • write matrix equations
  • compute X=A^(-1) B to calculate the solutions to systems of equations

Lesson 6: Augmented Matrices

Students will:

  • solve three-variable systems of linear equations using technology with matrices
  • rewrite systems of equations augmented matrices
  • solve three-variable systems using the reduced row echelon form command, rref ()
  • interpret the solution

Lesson 7: Systems of Linear Inequalities

Students will:

  • graph and write systems of linear inequalities

Lesson 8: Linear Programming

Students will:

  • Practice A and Practice B are suitable for use as in-class practice and homework. Two comparable forms are included for increased versatility.
  • The Exit Ticket is designed for a quick concept check at the end of the class period.
  • The Warm-Up is designed for next-day use to reinforce the previous day’s learning.
  • One-page display versions of the exit ticket and warm-up are included. Display the PDF page on a screen for student viewing and have students record their responses on notebook paper or scratch paper to save on printing.

ADDITIONAL RESOURCES EXCLUSIVELY AVAILABLE IN UNIT 3 INCLUDE:

  • 5 Concept Organizers offer complimentary alternatives for note-taking or post-lesson concept reinforcement.
  • The Mid-Unit Review (Forms A and B) provides an opportunity for students to practice the concepts they learned in the first part of the unit.
  • The Mid-Unit Assessment (Forms A and B) may be used as a test, quiz, or daily assignment to meet the specific needs of your students. Editable versions of Forms A and B are included as a .docx file for MS Word.
  • The Unit Review (Forms A and B) helps students focus on the key concepts studied throughout the unit.
  • The Unit Test (Forms A, B, and C) comes in two comparable multiple-choice forms (A and B) and one free-response form (C). The test key includes TEKS alignment for each question to facilitate easy data analysis. Editable versions of Forms A and B are included as a .docx file for MS Word.

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 judgment and experience when lesson planning.
