## Reflection: Learning Communities Organizing and Calculating Data with Matrices - Section 1: Warm Up

The Master Teacher Project and cc.betterlesson.com is a website that is free and invaluable to teachers and student achievement.  Collaborating with teachers across states has been amazing.  I have gained so much knowledge to share with other teachers, and my students.

Different strategies, methods, and ways of each school has been great to observe.  I will continue to interact with teachers on this website because I think online learning communities is one of the major ways we can improve Professional Development.  It is on the teachers own time with things they are having to do anyway.

I definitely would like to see more lessons on AP Statistics, and I think that it is an area that many math teachers need extra Professional Development.
