Teaching subtraction with regrouping

The video shows an alternative notation to the regular subtraction algorithm, where the numbers are broken down in to hundreds, tens, and ones, before regrouping (borrowing). For example, 56 is written as 50 + 6. The regrouping then becomes more transparent and easier for the student to understand.

As someone who is about to start attempting to teach a 2nd grader with math difficulties I found your video very enlightening. I really dislike TouchMath, as some kids have a hard time giving it up. I see 6th graders still trying to incorporate it while doing simple problems! What I like about this method is that it really reenforces place value and shows how the "borrowed" numbers are being moved around in the problem.

thanks for the help. But I have to say regrouping seems to be a huge waste of time.It feels like it is making something really simple and make it difficult.
