Math Tutorial

Good afternoon!  Our math today laid the foundation for regrouping (you might have learned the term "carry the one" when you were growing up--same thing, different word).  We did some great practice in class today, but there are a lot of steps involved, so I told the kids I would put a mini tutorial here to help them if they get stuck (and to help you)!  :)

Note:  While this may seem tedious and confusing, it is essential to helping 2nd graders understand why we regroup (or "carry the one"), helping them to understand the math on a deeper level, rather than just learning the process.

Step 1:  Show the problem
Show the problem on the workmat.  For example, problem 1 on page 23 is 24+7, so students will show 2 tens and 4 ones, then add 7 ones.

 Step 2:  Add the ones and tens
Add the ones, then the tens.  Write the sums on the homework sheet.  Then decide if you need to regroup (you will need to regroup if the ones have 10 or more).  On problem 1 of page 23, there are 2 tens and 11 ones.  We will need to regroup.

Step 3:  Regroup, if needed
If there are less than 10 ones, you can skip this step.
If there are ten or more ones, regroup on the workmat.  Circle 10 ones and move them over to the tens, creating a new ten. On problem 1 of page 23, we group 10 ones together and create a new ten.  There is 1 one leftover.

Step 4:  Write the sum
Once you have regrouped, write the sum.  On problem 1 of page 23, there are now 3 tens and 1 one leftover.  The sum is 31.

I hope this helps!
