The document describes strategies for teaching mixed-ability classes, including differentiating instruction, peer tutoring, and group work. It notes that students differ in their learning styles, backgrounds, and abilities. Effective strategies include preparing leveled activities; varying teaching methods; and giving attention, time, and support to different groups. Challenges include the time needed, but they can be addressed through planning, monitoring, and training students for independent work. The strategies aim to meet all students' needs and help them learn at their own pace.
