Step-by-step explanation:
The co-teaching model you're referring to, where the lead teacher and support teachers each deliver a lesson to a separate group of students, is known as the Parallel Teaching model. In this approach, the class is divided into smaller groups and each teacher takes responsibility for teaching the same content to their respective group. This allows for more interaction and personalized attention to students. It's a method often utilized to differentiate instruction and give more support where needed, effectively managing diverse learning needs within a classroom setting.
