Hi
This is the ultimate of manipulative. To do long division get a wad of
money, no more than 5 of each bill or coin needed.Only in your world you =
only
have dollars, dimes, and pennies (decimal notation) Take five children up =
to
the board and say they can "have" the money if they can share it equally. =
Show them that with $1.23 divided equally between five children you have =
to
share the dollar first. Tear one up into five pieces. They'll die!!
Suggest another way (make change so that you have
"useable" money-dimes. Continue sharing dimes until you find you have two =
left which you can't share with 5 people. They will hate that! Change =
into
pennies. Share evenly until you have only three pennies left. That's =
yours.
Only after a round or two begin silently recording your actions using the =
algorithm on the board
You can encourage children to bring in spare change. Then convert it =
into
Dollars and cents which must be divided. And disperse it daily. Of =
course
you can do this with fake money (same denominations) which will buy =
something
at the class store,
or you can just play who wants to be a "Penny-aire" and see who earns the
most in a day. Money is a great motivator. It teaches children to ":see" =
what a "fair" division or sharing really means. Have funl Ann, Maryland =
