I'm working on lesson plans for our next unit ... which is on Matrices. In past years students have only been taught how to solve them on their calculators. I'm glad we are going to teach them a bit more ... how to add, subtract, multiply by a scalar, and multiply matrices. Then we have been asked to teach them how to solve a system (2 x 2 only) using matrices ... using the determinant and inverse.
Here is my plan. I'd love to hear your thoughts ... trying to make what seems to be difficult and obtuse concepts real for my students. I don't usually use fill in the blank notes but this time around they seemed useful.
We are starting with an Oreo question ... in hopes to soothe (smooth) the path to the work.
