Type: Lesson/Unit Plan

Overview:

In Module 2, Topic A, students look at incidence relationships in networks and encode information about them via high-dimensional matrices. Questions on counting routes, the results of combining networks, payoffs, and other applications, provide context and use for matrix manipulations:  matrix addition and subtraction, matrix product, and multiplication of matrices by scalars.

Note: Although this module is identified as Precalculus and Advanced Topics in the EngageNY curriculum, it corresponds to the Algebra II and Algebra II with Trigonometry Alabama Courses of Study.

Content Standard(s):
Mathematics
