What is a 100 square?

A 100 square, often referred to as a "hundred chart," is a visual tool used primarily in mathematics to help students understand numbers and basic arithmetic concepts. It consists of a grid with 100 squares arranged in a 10x10 format, where each square represents a number from 1 to 100. This chart aids in teaching counting, addition, subtraction, and patterns, making it easier for learners to grasp numerical relationships. It's commonly used in elementary education settings.
