Section 2-6: Determinants and Inverses
Common Core Standard(s): N-VM-10, N-VM-12

I CAN: Understand that the zero and identity matrices play a role in matrix addition and multiplication similar to the role of 0 and 1 in real numbers. The determinant of a square matrix is nonzero if and only if the matrix has a multiplicative inverse.

I CAN: Work with 2 x 2 matrices as transformations of the plane and interpret the absolute value of the determinant in terms of area.

Unit Two Review: Matrices
Common Core Standard(s): N-VM-6, N-VM-7, N-VM-8, N-VM-9, N-VM-10, N-VM-12

I CAN: Use matrices to represent and manipulate data.

I CAN: Multiply matrices by scalars to produce new matrices.

I CAN: Add, subtract and multiply matrices of appropriate dimensions.

I CAN: Understand that, unlike multiplication of numbers, matrix multiplication for square matrices is not a commutative operation, but still satisfies the associative and distributive properties.

I CAN: Understand that the zero and identity matrices play a role in matrix addition and multiplication similar to the role of 0 and 1 in real numbers. The determinant of a square matrix is nonzero if and only if the matrix has a multiplicative inverse.

I CAN: Work with 2 x 2 matrices as transformations of the plane and interpret the absolute value of the determinant in terms of area.
