@SkyWhisperer - Yeah, there are a lot of open house activities for elementary school that teachers can use to open up a dialogue between the teachers and the parents.
At one function I attended, this teacher taught reading and writing. She wanted us to understand her approach to the writing process, so she took a completely interactive approach. She gave us all a pencil and paper and took us through a fifteen minute mini workshop, if you will, where she had us free write and then draft a simple personal story composition, no longer than one page in length.
A few parents volunteered to read their compositions to the class, and it was a fun time for everyone. I think that was the best thing the teacher could have done to help us understand how she taught her subject.
