Mastering Partial Products and the Distributive Property in Multiplication

The video tutorial explains how to multiply using partial products and the distributive property. It demonstrates two methods to find the product of 5 and 17: using an area model and using paper and pencil. The area model involves drawing a model to find partial products, while the paper and pencil method involves multiplying ones and tens separately before adding the results. Both methods arrive at the same product, 85.

• Associative and Commutative Properties

• Distributive Property and Partial Products

• Inverse Property and Distributive Property

• Identity Property and Zero Property
