Years ago, a principal of mine introduced us to T-charts for talking about expectations. On the left side of the chart was a heading Looks Like and on the right side of the chart was a heading Sounds Like.
Students were given an opportunity to develop the t-chart together and then it was posted as a reminder throughout the year of the expectations they had agreed upon.
Here is a sample of a chart my class created. You can get a copy by clicking the Lining Up Tips image below.
