Rounding+Decimals


 * Rounding Decimals**: This video shows how to round numbers using the "fairy tale" method. The fairy tell starts off with a wizard who asks a number to be rounded to a certain place value. That place value is confused and doens't know what to do (it's then circled). They are in luck though. They have a friend behind them called "bossy back" who tells them what to do depending on what number "bossy back" is. If it's 0,1, 2, 3, or 4 it shouts to the confused digit "stay the same forever more." If the bossy back is a 5, 6, 7, 8, or 9, then it tells the confused digit to bump up to the next number in line. As the story continues, the no longer confused digit turns to thank their bossy back but all that was there were zeros. So the no longer confused digit turned back around and the digits infront of them had all stayed the same.
