This is an example of a daily schedule for a multiage class. Notice that subjects, such as Math and English, are put into blocks of time which consist of different activities and groupings. This is a good strategy for any classroom but is particularly worth considering for this type of class.
This article focuses on Science but the ideas presented here certainly apply to other subject areas. I like the ideas for how to go about doing the same lesson with all students but in slightly different ways. Adapting for ability is always a good and necessary idea and in a multiage classroom, it can happen even more authentically to the benefit of all students.
So you've contemplated the pros and cons of your multiage classroom and how to make the most of the pros and make the best of the cons. Now you need some practical tips for actually managing your class. Learn how to focus on ability rather than age to create the best flow in your room.
Weigh the pros and cons in this in-depth article about multiage classrooms. One positive factor mentioned here that I can attest to as a teacher and parent, students in multiage classrooms tend to have more confidence and will be more willing to make friends with students in one or two grades above or below themselves. They will learn how to communicate and get along with children of different ages and that can be a wonderfully positive thing for students.
There are definitely great things about having a multiage classroom and you, as the teacher, should focus on the positives and really try to emphasize them. By being aware of the benefits, you'll be more likely to build on the good things and make them even better. Read about the pros and cons (and how the cons can be potentially resolved) to make the most of your multiage classroom!
