I had lunch with two good friends today. They both happen to be teachers. Anyway, one friend has been teaching for about 15 years; however, she recently moved to a new school and grade-level. She taught Kindergarten for years and years and decided to make the leap to 3rd grade. She said she loves the curriculum but that her teammates aren't willing to share anything at all! She said that they're not rude or mean, they just don't like sharing ideas or materials unless she directly asks them for something. It got me thinking: Am I the same way? Do I ever offer things to other teachers? Have I been helpful to my colleagues? What're your thoughts? Why is it that some teachers don't like to give up their strategies & materials?
