Now as I look to relate this to being a teacher leader, I still hear the same call to lead by example. Be the teacher you want your colleagues to be, be the leader you want your colleagues to be. It's not about enforcing non-negotiables or hoarding your ideas and resources. It's first doing what is best for kids, then telling others about what the students were able to do as a result. This isn't done in a "I'm the bomb.com and this is what I'm doing with my student" fashion. It's a "the kids were really engaged today when we did this..." fashion. This is when you share student work, student experiences and provide the opportunity for others to use your resources. You approach this humbly, so not to bring glory to yourself, but to shed a light on the goodness that is happening with student engagement and performance.
When you do things like that, you have the opportunity to get excited when a teammate decides the textbook isn't engaging enough for their students. So they come to you asking for the very thing you wanted them to use from the beginning, rich and engaging math tasks :-).
It is my belief that when a teacher switches from the textbook to GA state math frameworks, a math angel gets its wings!
