There are many of these on TPT. This is yet another set.
These participation cards are given to the students at the beginning of each lesson. As children participate, I collect their cards. If they have a card at the end of the lesson, they have not participated.
Cards are available in all of the main content areas and there is a generic set for other areas.
Corrected - Now with the number 15! :-)
It's Not Cute, But It Works.
