Addition with Regrouping

We are now moving on to 2-digit addition with regrouping.  Students are directed to continue to add the ones place first.  When that total is 10 or more, they need to mark how many ones below the equation, and how many tens (which it will always be 1) in the tens place above the equation.  For example:

    
        1
        2 7
     + 1 4
            1

Then, students need to add the tens place.  ** Don't forget to add the extra "1" you wrote up above!

       1
       2 7
    + 1 4
        4 1

Look for school work coming home that illustrates the strategy of regrouping.  This may help you to help your child understand the concept of regrouping.
