Leadership at school

I don't have a formal leadership role at school. We are very small and work in mostly individual capacities. There is one teacher for each grade level. I teach grade 5. If I had to express a role I would say I take the initiative to communicate with the 6-8 teachers to ensure that things I am doing in the classroom will directly impact the children and their ability to succeed in grade 6. I would say I collaborate well with the other teachers when the need arises. My leadership role involves a more informal capacity rather than a formal one. I find that I work better behind the scenes getting things done over being in the limelight. So this class should be interesting as I reflect on these things throughout the next 6 weeks.
