Calculate Partial Products
Calculate Partial Products is a skill on Pengi from Lesson 3: Use Arrays and Partial Products to Multiply in enVision, Mathematics, Grade 4.
Key Concepts
The partial products algorithm uses the distributive property to solve multiplication. A multi digit number is broken into the sum of its place values (expanded form), and each part is multiplied separately before adding the results. $$a \times (b + c + d) = (a \times b) + (a \times c) + (a \times d)$$ Each partial product can be represented as a section of an array, showing how the total product is composed of smaller, manageable parts.
