3.OA.5. Apply properties of operations as strategies to multiply and divide.2 Examples: If 6 × 4 = 24 is known, then 4 × 6 = 24 is also known. (Commutative property of multiplication.) 3 × 5 × 2 can be found by 3 × 5 = 15, then 15 × 2 = 30, or by 5 × 2 = 10, then 3 × 10 = 30. (Associative property of multiplication.) Knowing that 8 × 5 = 40 and 8 × 2 = 16, one can find 8 × 7 as 8 × (5 + 2) = (8 × 5) + (8 × 2) = 40 + 16 = 56. (Distributive property.)

Multiplication is the repeated addition of equal groups. The number of equal groups and the number in each group are the factors. Once you know those factors, just apply these four properties of multiplication. Learn more about multiplication with... this cartoon animation from StudyJams. A short, selfchecking quiz is also included with this link.

Ms. Meyer teaches about the associative property. She models an example of association with character figures. Next, she uses mathematical examples to answer these questions: What is the associative property? Why does it have the name it does? How ...can you recognize it when you see it? (06:38)

This video indicates it is for prealgebra, however this video would be good for anyone who is reviewing or learning multiplication. This video starts with the different ways people write multiplication equations, using a dot, the times symbol, or pa...renthesis. They talk about what multiplication means, it is repeated addition. Then they discuss the commutative property for multiplication. They show this using the number line. They show this using many different problems. The video concludes with using subtraction to find a number close to the number you know, for example if you 7 x 10 is 70, then what is 7 x 9? Video is good quality and good for all students as review or initial learning of the concept. (09:52)

This video indicates it is for prealgebra, however this video would be good for anyone who is review mulitiplication and its properties. This video begins with showing the Commutative Property for Multiplication, which states when two numbers are sw...itched they will have the same product. An example is given with three numbers, this is done from left to right (order of operations). Then they switch what is mulitiplied first the product is the same, this is the Associative Property for Mulitiplication. Additional examples are done. Then they show how to multiply numbers that equal something easy first and then do the rest of the numbers, for example 2 x 3 x 4 x 5, do the 2 x 5 first because it is 10 then do the 3 x 4 is 12, then 10 x 12 is 120. They also do more complicated problems using mental math, which is a good introduction for more advanced students. Video is good quality and good for all students as review or initial learning of the concept.
