Organize classroom participation into categories that you want to grade by, like answering questions, reading aloud, asking questions or giving class presentations.
Create a folder to keep participation marks. Have each student's name listed with boxes next to each name, with one box for each category of participation you want to grade.
Make marks in the folder every time a student fulfills one of the categories, such as answering a question or participating in a class discussion.
Determine what grade will be given for what marks. For example, three marks in each box may equal a B, while two marks in each box may equal a C.
Encourage students to participate in class. Some children will be shyer than others and will need your encouragement to raise their marks.
