Division by 1digit numbers:
Partial Quotients Methodhttp://www.youtube.com/watch?v=8Ft5iHhauJ0
When we know how many groups there are and how many things are to be shared, but we don't know how many are in each group, we divide to share equally. Division is the inverse of multiplication. Inverse operations undo each other. For example: 5 x 20 = 100 and 100 divided by 20 = 5. Division is a simpler way to do repeated subtraction. Divisibility Rules:
Any number, except 0, is divisible by 1 and itself. For example: 30 divided by 1 = 30 and 30 divided by 30 = 1. Division of 0 is a special case of divisibility because any number, except 0, will divide into 0. Zero divided by any number, except 0, is zero. For example: 0 divided by 3 = 0. Division by 0 cannot be done. When we divide we can use the expanded division algorithm. Go to the Click Me button below for expanded algorithm power point to see how to use the division algorithm.
