Whole-Group Fluency materials include oral fluencies and whiteboard fluencies. Each day, teachers choose one fluency to complete as a class as a fun warm-up. This whole-group warm-up engages the community of learners and builds number sense. Each student should have an individual whiteboard so each student has an opportunity to show their pictorial and abstract representations. Fluency activities are opening activities with two instructional purposes – one is fun practice of previously learned ideas to develop procedural fluency and retain content and the other is a warm-up for upcoming content.
