## Lesson Plans

Having Fun with Matrix Multiplication:

In this lesson, students learn how to multiply matrices using paper-and-pencil and GeoGebra. Students will use matrix multiplication to represent and solve real-world problems.

Type: Lesson Plan

Using matrices to model the dynamics of demography:

In this lesson, students will formulate, implement, and interpret a simple demographic model in which birth rates and survival rates are constant for each age cohort. The model will have the form x'=Ax, where x is the population distribution at some time, x' the population 20 years later, and A a (Leslie) matrix that contains the problem parameters. Using a context should help students better understand the meaning of matrix multiplication and its role in linear discrete dynamics.

## Presentation/Slideshow

Matrices:

This resource is a PowerPoint presentation and a form for guided note taking to be used while viewing the presentation about Matrix Operations. It begins by defining matrices and identifying types of matrices. It then goes into how to add, subtract, and multiply matrices, including how to use scalar multiplication. The final portion deals with finding the determinants of 2x2 and 3x3 matrices and Inverse Matrices.
