The Four Square is used for bell work or beginning of lesson warm up for math. It goes great with Envisions Math Curriculum. All four squares have a specific purpose, review, touching the lesson for the day, prepping for test success, and a concept that is typically challenging for kids. I display the 4 square of the day on the board and students enter the classroom in the morning to immediately start their problems in their math journals. This allows for great morning starts and transitions whe
