Number value is a foundational concept for young mathematicians, so help them visually comprehend it using this activity. Learners "make" three numbers by completing boxes with any additional squares needed. For example, if they need to make the number 6, and the box has three squares, they would need to add three. There are three numbers, each with three boxes to complete. For each box, learners write an accompanying number sentence. They'll use addition and subtraction.
