Using Partial Products to Apply the Distributive Property
Partial products is a math strategy that helps 5th grade students decompose a multiplication problem into smaller, more manageable parts. Using area models, students can break down the problem into two separate parts: the product of each factor and the sum of the two products. By using partial products, students can apply the distributive property to solve the multiplication problem.

3 Digit By 2 Digit Multiplication Using Area Models
Area models are a visual way to represent multiplication. They can help you visualize the base-ten structure of numbers. To solve a 3 digit by 2 digit multiplication problem, you will need to break down each number into expanded form, draw an area model for each, and then add the area models together. The area model can help you solve any 3 digit by 2 digit multiplication problem quickly and accurately.
