Use arrays to show different ways to multiply and get the same solution.  # Multiplying Single Digit Numbers - Arrays & the Commutative Property (3.OA.1, 3.OA.3)

## By Worksheets and Walkthroughs

This video walkthrough guides the students through two single digit multiplication word problems. Solutions are represented as arrays while proving the commutative property.  # Multiplying: 2 digits times 1 digit (with carrying) | Arithmetic | Khan Academy

We use something called the standard method which involves writing the larger of the two numbers on top. Watch.  # Multiplying: 4 digits times 1 digit (with carrying) | Arithmetic | Khan Academy

## By Khan Academy

This is getting fun! We're now multiplying FOUR digits times one digit. Remember to carry!  # Multiplying: 3 digits times 1 digit (with carrying) | Arithmetic | Khan Academy

## By Khan Academy

We're carrying numbers in this example. Everyone needs a hand now and then, right?  # FOIL method for multiplying binomials example 2

This instructor in this ten-minute video, Sal Khan, demonstrates how to multiply polynomials. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. The student or educator may want to open the video to 'full screen' as the instructor is using a black background and the writing is small  # Multiplying Polynomials
