How do I multiply matrices?
Standard: MGSE9-12.N.VM.7, MGSE9-12.N.VM.8
Add, Subtract, and multiply matrices of appropriate dimensions. Multiply matrices
by a scalar to produce a new matrix.
Instruction: Discussion & Group Practice
Differentiation: Individual pacing/questions
Class meetings – SLO Pre-test
How do I find determinants and inverses (2x2 only)?
Standard: MGSE9-12.N.VM.10
Understand that the zero and identity matrices play a role in matrix addition and
multiplication similar to the role of 0 and 1 in the real numbers. The determinant of a
square matrix is a nonzero if and only if the matrix has a multiplicative inverse
