Description

Systems of Equations and Matrices (PreCalculus Curriculum Unit 10) | All Things Algebra®

DISTANCE LEARNING UPDATE: This unit now contains a Google document with:

(1) Links to instructional videos. Videos are created by fellow teachers for their students using the guided notes from the unit. Please watch through first before sharing with your students. They might not always be perfect but we are trying our best to help out where we can in a very limited time.

(2) A link to a Google Slides version of the unit. Each page is set to the background in Google Slides. There are no text boxes; this is the PDF in Google Slides. We are unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead!

This bundle includes notes, homework assignments, four quizzes, a study guide, and a unit test that cover the following topics:

• Two-Variable Systems of Linear Equations Review (Graphing, Substitution, and Elimination Methods)

• Two-Variable Systems of Linear Equations Applicationsc

• Nonlinear Systems of Equations (Solve Graphically and Algebraically)

• Three-Variable Systems of Equations

• Three-Variable System of Equations Applications

• Matrix Addition, Subtraction, and Scalar Multiplication

• Multiplying Matrices

• Determinants

• Inverse Matrices

• Matrices on the Graphing Calculator

• Solving Systems of Equations with Cramer’s Rule

• Solving Systems of Equations with Inverse Matrices

• Solving Systems of Equations with Gaussian Elimination and Augmented Matrices

• Solving Systems of Equations with Gauss-Jordan Elimination

• Recognizing Special Solutions (No Solution and Infinitely Many Solutions)

• Partial Fractions (Proper and Improper Expressions)

• Partial Fractions with Special Case Factors: Repeated Linear and Prime Quadratic

NEW: Assessments are now EDITABLE! Now you can easily make multiple versions or customize to fit your needs! PowerPoint and Equation Editor (usually built in to PowerPoint) are required to edit these files. There is a folder titled “Editable Assessments” when you download. This is where you will find editable versions of each quiz and the unit test.
