In my classroom, thumbs up, down and sideways are a common sight! We self- assess ourselves to track our learning. It is a quick and efficient, non-judgemental way for my students and I to share our learning.
The system is a four scale system. There are words and illustrations to match each of the levels of learning. The students simply hold up their thumb or thumbs and I know if anyone's learning has stopped. I can quickly pull a small group to review or provide some students with an enrichment activity.
If you're looking for a simple, class-wide assessment tool...this is it!
I hope you can offer positive feedback for my provide. Please don't hesitate to ask a question as well!
Thank you and Happy Teaching!
