I am an interventionist, so I have to teach students on all levels. As a general routine, my students come in, complete the warm-up in the whole group, and I instruct in the whole group. After a mini lesson, I allow students to break in to small groups and work individual problems. To ensure every one is working, I offer incentives for students to earn while working. during this time, I sit with the struggling students as a form of remediation. Also, it's important to give formative assessments to ensure your methods are functional. If they are not, don't be afraid to scratch them and try again!

One thing that I do to differentiate instruction is level the instruction around the amount of direct instruction that is required. For example, beginner students may be pulled into a small group to receive the instruction with limited independent reading of the content. The intermediate students could read independently to learn the material. After following up with these students, they could have an assignment to further their understanding of the material. Expert level students could be participate in more of a project-based learning activity. Perhaps, they could be assigned a product to complete. They would need to independently learn the material to complete the product.

I would do this by creating small groups according to their ability levels. I also take my higher students and let them help the lower or intermediate level groups. This ensures that each group of students is getting remediation or is able to extend their learning by "teaching" other students.
