Checking Division

          We have just about wrapped up our multiplication and division module.  However, I did want to post another resource here that matches an anchor chart in our classroom.  These are the steps that you can use to check your division.

I hope that this was helpful :)

Factor Rainbows

          When finding the factors of a number we look for the numbers that can be multiplied together to create that number.  We have been using what I call a "Factor Rainbow" to keep our answers organized.  You can use skip counting or division to help you find your factors.

Creating a Factor Rainbow:

1. Start with the number (24) you are looking for times 1, (e.g. 1 x 24 in above example) and record the factors and connect with an arch/rainbow.

 2. Counting by ones go to the next number (2) and then skip count by that number to find out if you can arrive at the number you are looking for (24). If you do, record the two factors and connect with an arch/rainbow.

3. Counting by ones go to the next number (3) and repeat the steps.

4. You can stop checking when there are no more whole numbers between the factor arches. For example after I check five in the above example I can stop because there are no whole numbers between 5 and 6 and 6 is already on the rainbow. J

***You can also use division to help you.  Here’s how, use the standard algorithm.  If you have a remainder then that number is NOT a factor!!!  

Division

          Back on November 2nd we began dividing using the standard algorithm (AKA long division).  Parents you are going to love, because this is the strategy that you are familiar with, however, it may be challenging for the students because unlike the multiplication strategies it is not a conceptual strategy.  In the student's math journal we put an entry color coding the steps.  I am hopeful that this colorful visual representation will help with the memorization of the steps.  Below you will see my entry.

          This will take some time for the students.  The best advice repeated practice.  You can print worksheets with 1-digit divisors and 2-, 3-, or 4-digit dividends for your child to practice.  Or you can make it a game by rolling dot cubes (dice) or flipping playing cards to create the problems.  Making it a game will be more fun and your child will stay engaged longer :-)

Moving . . .

         OK, so I was so excited to begin blogging again . . . and then we sold our house.  Which was a HUGE blessing.  However, we had lived in the same house for ten and a half years and had accumulated a LOT of stuff!!!  So it has been a little crazy trying to pack, teach every day, move, teach every day, unpack, and did I mention still teach every day?!?

          Bill, Audrey (the world's greatest dog), and I are getting settled and hopefully I am back (for real this time).
