A fun slide to have on the board while holding a thumb-o-metre session
What is Thum-o-metre?
Using a thumb-o-metre is a great AfL technique. The teacher asks students how they feel about a topic e.g. how confident do you feel using the SUM function in excel. Student indicate with thumbs up, down or level. This gives the teacher a really quick overview of how well the whole class understand the topic.
