Unit 5 Matrices L2 MATRIX MULTIPLICATION

First: There will be a 10 question assessment on Friday over Matrix Operations. It will count as a test grade. These concepts will be covered:
            Matrix Addition
            Matrix Subtraction
            Scalar Multiplication 
            Simplifying Expressions with More Than Two Matrices
            Matrix Multiplication

If you missed Monday or Tuesday of this week, I expect you to catch up by viewing the slideshow posted earlier this week and getting your work from the sub.

Second: You need to view the slideshow to learn the new concept of Matrix Multiplication.
The slideshow consists of many slides, but that is because I made a new slide almost every time there was some incremental change, no matter how small.

It is possible my hard work putting together these slides was fruitless. If this is true, and you are still confused after viewing the whole thing, I attached links to 2 YouTube videos over matrix multiplication on the last slide. The first one has narration almost exactly how I would teach it if I were in class, and the second is a well produced video with quick and concise methods for matrix operations.

Once you view the slideshow, you will be able to complete A 5 - 2, which has 8 operational problems, 1 application problem, and 1 review problem about writing the equation of a line. Only 1 of the problems from # 1 - 8 is NOT POSSIBLE. This assignment is due on January 15, 2015. You will receive another assignment over matrix multiplication on Thursday as well, though there will not be a slideshow to view. Use your time wisely.

Remember, you should not have to ask permission. Instead of asking sign in with another google account, which MUST be your melissaisd.info account. If it does not open in presentation mode, click present which is located in the top right corner of the screen.

Unit 5 Matrices L1 NO NOTEBOOK

First things first: I AM STILL ALIVE!!!

Second: I have experienced a ton of pain and discomfort since NYE so I am in the care of physicians in San Antonio for just a few more days. I had 2 surgical procedures last week, and am now in the process of recovery. I apologize for any inconvenience caused by my absence.

Third: You need to watch this slideshow to learn basic matrix vocabulary, along with the steps for matrix addition, matrix subtraction, and scalar multiplication. Yes, this is new material. There is no notebook made for this unit, so you do not actually have to copy anything down at this moment. Please pay attention to what is happening. Once you view the slideshow, you will be able to complete A 5 - 1 which the sub should have for you in class on January 12, 2015. This assignment is due on January 14, 2015.
