Commutative and Associative Properties

 

 

I have found that even after defining these two properties, students do not really recall or understand them. I added these four practice problems and focus the guiding questions on which method would be easiest or most appealing for mental math.

After we worked through the above problems, students were able to identify the properties when asked and even identified them when they were applied later on.
