Math instruction in School 28 is based on the workshop model. Each lesson starts with an opening, which is approximately 5-10 minutes, which is designed to allow teachers to introduce the daily learning target, unpack lesson objectives, and activate prior knowledge of the upcoming content. Next, each lesson has a concept development. Here, teachers continue to build off of the daily learning target and help students understand strategies that can be used to solve complex math problems. During this time, students may be working in small groups with the teacher, brainstorming with other students, or engaging with technology. Finally, at the conclusion of each lesson, is a formal lesson closing. During this time, teachers typically do a check for understanding of the lesson to make sure students have grasped the lesson objectives. This is called an exit ticket and teachers use this data to drive future lessons.
