Carol - I think of the determinant as the "size" of the matrix. Might
be a good enough explanation for Algebra II. :-) And here's a link
that might help with instruction:

Does any one have a good handle on teaching how to find the
determinant of a matrix and what it means? I have a very shaky grasp and
any good resources you know would be helpful.

I not only help students with the GED, but I teach all the High School
courses as well. I have two students needing to complete Algebra II.
