A couple students every course are frequently tardy and absent. I attempt to "catch-up" these students by allowing them to take home quizzes and turn in work late. Taking care of these students takes time and is sometimes distracting from the next lesson. Giving these students the opportunity to succeed is important; however, missing a few lessons and lab exercises should be extremely detrimental to their grade. Not failing these students is very hard and I do my best to help them get through. What are strategies for allowing students to catch-up while at the same time move on with the course content?
