[QUOTE="Pribilof, post: 16209903, member: 155968"] I'm dying over here! She busts out the coffee maker! LOLOLOLOL! Obviously, the best way to teach the 4 properties of multiplication is through this convoluted "new" method rather than just defining the terms and giving examples! (And the "new" teacher still has this old school process to add up four numbers... isn't there some "new" way to do this so poor little johnny doesn't have to carry the one?) Multiplication Properties There are four properties involving multiplication that will help make problems easier to solve. They are the commutative, associative, multiplicative identity and distributive properties. [i]Commutative property:[/i] When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For example 4 * 2 = 2 * 4 [i]Associative Property:[/i] When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors. For example (2 * 3) * 4 = 2 * (3 * 4) [i]Multiplicative Identity Property:[/i] The product of any number and one is that number. For example 5 * 1 = 5. [i]Distributive property:[/i] The sum of two numbers times a third number is equal to the sum of each addend times the third number. For example 4 * (6 + 3) = 4*6 + 4*3 And for the kids that just can't figure it out... [ATTACH=full]1576751[/ATTACH] [/QUOTE]
