Description
This lesson builds on the work in the previous lesson in which students modeled transportation networks with matrices. The primary example used in Lesson 1 was a set of bus routes that connect four cities. This situation is used to help students discover and define multiplication by a scalar (N-VM.C.7) and matrix addition and subtraction (N-VM.C.8). This lesson helps students understand the meaning of this matrix arithmetic.
