Multiplication Trick: Multiples of 10 and Place Value Patterns!

Join us as we develop procedural fluency and conceptual understanding of multiplying numbers that are multiples of 10 using place value patterns and the associative property.

This lesson answers the questions: What is number sense? How do I multiply numbers that are multiples of 10? What are place value patterns? What is the associative property? What are the shortcuts and tricks for multiplying?

@4:58 The commutative property tells us that the order does not matter. The associative property tells us that the grouping does not matter. Great video, but that misconception should probably be cleared up so students don't confuse it anymore than they already do!

excellent except that associative property refers to grouping order. wish you would fix that

Please correct the video, Associative property is incorrect. The Commutative property is that you can multiply any order. Associative property refers to grouping symbols. I like your video but please make that one correction so I can show it to my students.

I get the zeros but what if there is no zeros? Like 45 × 51 = ?
