Grade 3 - Multiplication - Decomposition or Partial Products

In this video, we'll explore how to simplify multiplication by breaking down numbers into smaller, more manageable parts. This technique, often referred to as partial products or decomposition, allows students to work with simpler numbers to make mental math easier.

We'll demonstrate how to split a factor into parts, use an area model to visualize the process, and then combine the partial products to find the final answer. These strategies help students understand multiplication at a deeper level and develop their mental math skills, making complex problems more approachable.
