Lesson Plans

Name Description
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.

Using matrices to model the dynamics of demography

In this lesson, students will formulate, implement, and interpret a simple demographic model in which birth 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.
