"Bell ringers" are activities or tasks that teachers use at the beginning of a class to engage students and prepare them for learning. These activities can include questions, puzzles, or short writing prompts that encourage students to think critically and focus on the lesson ahead. The goal is to create a smooth transition into the day's subject matter. Typically, bell ringers are designed to be completed in a few minutes, allowing students to settle in and get ready for the lesson. They can also serve as a way to review previous material or introduce new concepts, making them a valuable tool in the classroom.
