Expanded Notation
(When breaking up a number, we usually break it up by each digit.  Any number after the first digit should be zero(s).  You can check your work by adding all the numbers together and you should end up with your original number.)

(We can also break up multiplication problems)

(Scientific Notation can also be a different way to show the result of the broken down numbers)

Number Bonds - Division
(Decomposing a number to make it more friendly)

    I liked how in the pictures the problems were broken down step by step. Although I think it might have been nice to also have the written step by step of the problems to follow along.
