    Rounding Story

    One of the teachers in my school just taught me this way of teaching rounding and my kids really loved it. You tell a story about a criminal (the number to be rounded), a judge (the number that determines the rounding) and the jury (the rest of the numbers. In order to find out whether or not the crimimal has to stay in jail he must go to the judge and ask. If the judge is a strict one (a number of 5-9)then he must stay in jail one more year. He goes up one number. Then the judge and the jury go to lunch and are replaced by zeros. If the judge is a weak one (number from 0-4) he or she says ahhh you can go and i won't make you change. Then he goes to lunch with the jury and the numbers are replaced with zeros. So in the number 457 - where 4 is the criminal, 5 is the judge and 7 is the jury. 5 is a strict judge and makes the 4 stay in jail one more year. The 4 becomes a 5 (because the judge is strict and makes hime change). Then the judge goes to lunch with the jury (the 7) and they are replaced by zeros. The number becomes 500.

    Good luck!!!
