In this blog post by Kathleen Perret on “Learning is Growing”, she gives a list of great ideas for informally assessing the learning of your students.  These are quick techniques to use at the end of a lesson just to check if your intended message got across.  Although I have used some of these, there are a few new ideas that I think would be well-worth trying – such as “Chalkboard Champs” or “Rock, Paper Scissors”.
