Rounding
By Mr. Walker
UsingThe Cinderella Story
Locate Cinderella
1,365,429
In any given number, Cinderella is the digit that is underlined
If there are no digits underlined, then the directions will tell you what place Cinderella is in
1,365,429
1,365,429
Round to the ten thousands place
The Fairy GodmotherCinderella can’t go to the ball without some help from the Fairy Godmother
1,365,429
The Fairy Godmother always comes in on Cinderella’s right
She is a little round, so circle the Fairy Godmother
Does She Have the Power?
To get Cinderella to the ball, the Fairy Godmother needs to do a bit of magic, but it all depends on the power in her wand
If the power in her wand is 5 or more, then she has enough power to change Cinderella
If her wand is 4 or less then Cinderella is out of luck and will stay the same scrubbing the floors

Does She Have the Power?
1,365,429
If we look at our number, the Fairy Godmotherhas a 5, so she does have enough power to change Cinderella
1,365,429When the Fairy Godmother uses her power to dress up Cinderella
Cinderella’s number goes up by one
1,375,429
Bye Fairy Godmother
1,375,429
The Fairy Godmother’s job is done and her power is all gone, so she disappears (the 5 changes to a 0)
The rest of the numbers after the Fairy Godmother get changed to zeros as well
1,370,4291,370,000
The Sisters
1,370,000
After changing and rounding, don’t forget that the evil step sisters (the numbers in front of Cinderella) always follow her around to make fun of her
They go to the ball with her if she gets changed and they stay at home mocking her if she does not get changed (always put thosenumbers back on the front when you are done)
Not Enough Power
1,363,429If we look at our number, the Fairy Godmotherhas a 3, so she does not have enough power to change Cinderella
Lets try a number where the Fairy Godmother does not have enough power to change Cinderella
1,360,000
The Fairy Godmother tried her best but could not do it, and now what little power she had is gone, so she disappears (the 3 changes to a 0)
The rest of the numbers after the Fairy Godmother get changed to zeros as well
1,360,429
The Sisters
1,360,000
After changing and rounding, don’t forget that the evil step sisters (the numbers in front of Cinderella) always follow her around to make fun of her
They go to the ball with her if she gets changed and they stay at home mocking her if she does not get changed (always put thosenumbers back on the front when you are done)
