This week we began our multiplication and division unit. This is a new unit for 3rd graders and they are very excited about it. Research shows that students learn math concepts best using a 3-step framework called the concrete-representational-abstract (CRA) approach. During the initial stage of introducing a new skill, students use concrete objects to physically model the concept. Once there is a solid understanding of why and how the concept works, students move into the representational stage where they turn the concrete models into pictures. Finally, in the abstract stage, students learn the algorithm that symbolizes the concept using numbers and mathematical symbols. Entering the abstract stage too soon prevents students from developing a deep understanding of the mathematical process. As we begin our multiplication unit, we are moving slowly using the CRA approach so that students' brains can make connections between what they already know about numbers (skip counting, making equal groups, doubles) and the new concepts they're learning. There's more to multiplication than just memorizing the facts!
