Lessons 1–3 Self Assessment 1

For each statement, rate your understanding according to the continuum, and then provide evidence for your rating.

	I understand and can do it accurately.	I understand most of the time, but I’m still working on it.	I don’t understand this yet.
I can solve a linear system with $n$ equations and $n$ unknowns using row reduction of matrices.
Evidence Rating
I can multiply an $m \times n$ matrix by an $n \times p$ matrix and use matrix multiplication to model real world contexts.
Evidence Rating

	I understand and can do it accurately.	I understand most of the time, but I’m still working on it.	I don’t understand this yet.
I can find the determinant of a $2 \times 2$ matrix and use the determinant to decide if a matrix has an inverse.
Evidence Rating
I can use inverse matrices to solve systems of linear equations by finding the inverse of a $2 \times 2$ matrix by hand and the inverse of an $n \times n$ matrix using technology.
Evidence Rating
I can identify and apply strategies for solving linear systems of equations, including graphing, substitution, elimination, row reduction of matrices and using inverse matrices.
