G2's first video this year!!
At the beginning of the school year, we got these great new Mac computers that most of the teachers are still learning how to year. This week we received a very helpful tutorial from one of our aides, Mr. Lugo. Thanks to him, I was able to put together our first video on electromagnets.
It is a little rough around the edges, but not too bad for a first try.

Multiplication Facts and Division Rules
Associative Property
changing the way the factors are grouped does not change the product
2 x (8 x 9) = (2 x 8) x 9
Commutative Property
changing the order of the factors does not change the product
2 x 8 = 8 x 2
Identity Property
1 x a number = the smae number
1 x 55 = 55
Zero Property
0 x any number = 0
55 x 0 = 0
Division Rules
1. Any number divided by 1 = that number
55 divided by 1 = 55
2. Any number divided by itself = 1
55 divided by 55 = 1
3. Zero divided by any number is 0
0 divided by 55 = 0
4. You cannot divide a number by 0
