Operation Mathematics

This resource can be used to practice solving systems of equations with matrices. Students write systems of equations as matrix equations, write matrix equations as systems of equations, and solve a system of equations using inverse matrices. An answer key is provided.

This activity asks students to find the area of a triangle by applying the determinant of a 3x3 matrix. Students check their answers by graphing the triangle on a coordinate plane and using the area formula. An answer key is provided.

This resource gives students a conceptual understanding of inverse matrices. At the end of the investigation, students should recognize the relationship between a matrix, its inverse, and the identity matrix. First, students investigate how the commutative property relates to multiplication with the identity matrix. Next, students multiply inverse matrices to discover the identity matrix. A key is included.

This resource includes 2 matrix activities. One activity guides students through dilations and translations; the other activity guides students through reflections and rotations. A key is included for each activity.

Students learn how to recognize row operations that are used to transform matrices in this activity. A key is provided.

This bundle includes seven individual assignments on matrices. The following topics are each covered on an assignment: scalar multiplication, matrix multiplication, matrix transformations, matrix determinants, matrix inverses, inverse matrices and systems, Cramer's Rule and augmented matrices. An answer key is included for each assignment.

This assignment covers geometric transformations using matrices. Translations, dilations, rotations, and reflections are included. An answer key is provided.

This resource includes 3 activities: Scalar Multiplication Activity, Matrix Multiplication Investigation, and Matrix Multiplication Activity. A key is included for each activity.

This resource can be used to practice solving systems of equations with Cramer's Rule. Students also write augmented matrices for a given system and write systems of equations for an augmented matrix. An answer key is provided.

This resource can be used after teaching about inverse matrices. Students use matrix multiplication to determine whether matrices are multiplicative inverses, find the inverse of matrices if they exist, and solve a matrix equation using inverse matrices. A key is included.

This resource can be used to practice matrix multiplication. Students explain whether a given matrix multiplication is defined or undefined. They also practice finding the product of 2 matrices and determining the dimensions of a product matrix. A key is provided.
