Matrices Playlist for Algebra 2
Of course, it's impossible for me to think of a matrix without thinking of the iconic film, The Matrix. What's fun is that now you can learn exactly what a matrix is, and how to work with them! Namely, the main topics are calculating the determinants of 2x2 and 3x3 matrices, as well as inverse matrices, solving systems of equations, multiplying matrices, and other operations with matrices. We even go spy-like, and learn how to encode and decode messages using inverse matrices. It's pretty cool. YAY MATH!
At the top of each video, you can access that lesson's worksheet and quiz.
The worksheet contains the exact problems we cover in the video. Just print the sheet and work along with the class.
Take the quiz right after the video, to see how well you learned it.
To access the worksheet and quiz at any time, simply pause the video.
