Here's a link to some good division games that can be played on the smartboard.

I really like "draggable division" to go through all the steps...you can easily have students doing the problems at their seats while others are at the SB. I like that it's on graph paper to show how to line up the numbers. I also sing a song to teach the steps:

First you estimate what the answer might be

Then you div-i-ide

and check it by mulitplying

subtract the answer

and bring it on down

bring it down,

look around,

are you at the end?

If the answer is yes then you write the remainder, if no then start over. It's got a jazzy tune and we use hand motions as well.

For divide: hands in fists in front of you (to look like the division symbol)

For multiply: hands in an x

For subtract: hands out like a plane (again to look like the symbol)

bring it down: grab at the ceiling and bring it down to your waist

Look around: hand over eyes, look back and forth

Are you at the end: shrug

I find that this really involves them in the method and they'll often hum the tune while doing a problem, it allows children a fun way to remember and still work at their own pace.

Hope that helps, good luck.
