Regrouping

By Mrs. McLaughlin's Class


In class we have talked about regrouping for 4 weeks.  We know about the Manly Man Club for subtraction.

First, look for Wimps in the top right corner.  That's a little number on the top in the ones column.

Then we check for Bullies.  A bully is bigger number in the ones column on the bottom number.

If the Wimp is too small to handle the Bully, the Wimp calls the Manly Man Club to help.  The Manly Man says I'll be right over.  The Manly Man is as strong as ten men.  We add his strength to the ones column on the top.

Now we take away one Manly Man from the Clubhouse and subtract in the ones column from top to bottom.  Then go to the tens column and subtract there.

After you subtract the ones column and the tens column you have to write the answer under the numbers.

For example, 53 - 38 = 15

We had to borrow from the Manly Man Club.  The 5 becomes a 4 and the 8 becomes 18.  Then we write the answer after we subtract the ones and the tens.
