Teaching in Sunday School

Well I have been called to be the 6/7 teacher in primary. I had managed to not have a calling for over a year so I knew it was coming. This actually the first time being a teacher in primary. I have always been in the primary presidency. My class is small and we are learning each other ways and I think coming together nicely. These children do not realize they are my test students. I will trying out my teaching strategies out on them. Why do they act different in primary?? I'm not sure. I'm learning things about myself and things I need to work on. The lord is always teaching us!!
