A "Bell Ringer" is a term often used in educational settings to describe a brief activity or question that engages students at the beginning of a class. This activity is designed to capture students' attention and prepare them for the lesson ahead. It can include a quick review of previous material, a thought-provoking question, or a fun fact related to the day's topic. Typically, Bell Ringers are used to promote critical thinking and encourage participation. They can be tailored to various subjects, such as math, science, or literature, and help establish a routine that signals the start of learning.
