Product Description
Adding and Subtracting Matrices in a PowerPoint Presentation

This slideshow lesson is very animated with a flow-through technique. It was made for my Algebra 1 class, but can be used for lower grades. This lesson was one of a chapter that was used as a review for all previous grades. The lesson teaches how to plot on a coordinate plane and use a T-table to solve problems. This lesson has a unique way of remembering how to plot a point. The visual in this lesson is well worth it. The students will never again get the x and y coordinate mixed up.

The presentation has 32 slides with lots of whiteboard practice. Use as many or as few of the problems to help your students help learn each concept. For more PowerPoint lessons & materials visit:

Students often get lost in multi-step math problems. This PowerPoint lesson is unique because it uses a flow-through technique, guided animation, that helps to eliminate confusion and guides the student through the problem. The lesson highlights each step of the problem as the teacher is discussing it, and then animates it to the next step within the lesson. Every step of every problem is shown, even the minor or seemingly insignificant steps. A helpful color-coding technique engages the students and guides them through the problem (Green is for the answer, red for wrong or canceled numbers, & blue, purple & sometimes orange for focusing the next step or separating things.) Twice as many examples are provided, compared to a standard textbook. All lessons have a real-world example to aid the students in visualizing a practical application of the concept.

This lesson applies to the Common Core Standard:
Vector & Matrix Quantities HSN-VM.C
Perform operations on matrices and use matrices in applications.
8. Add, subtract, and multiply matrices of appropriate dimensions.

Please note that the PowerPoint is not editable.

If you need an alternative version because your country uses different measurements, units, slight wording adjustment for language differences, or a slide reordering just ask.
