## Reflection: Developing a Conceptual Understanding What are Matrices? - Section 2: What is a matrix?

Today the students used reading strategies to understand the definition of matrices. After the students had discussed question in the small groups we worked as a class to understand the definition. Most classes came had a few common questions like what is the "a". The questions in the example are in blue and the answers to what we read are in green.

My last class had some very good questions for understanding. The questions shared with the class are excellent for understanding the definition. The bottom question led to some interesting discussion and a student giving a great definition to others.

Many classes compared a matrix to a multiplication chart. I have several student in Project Lead the Way classes and saw their design matrices as what we were doing. One student discussed a spreadsheet while others saw the entries as points on a Battleship Game board.
