Subject: Re: Subtraction

Another counting idea I learned at a Dr. Lola May workshop is to count
either up or down in two steps using 10 as a stopping point.  Students
will hopefully know combinations from the starting number up to 10 and
then 10 to the "teen" number.  In this problem, they would think of 8
to 10 as 2; and 10 to 13 as 3.  The student would add 2 + 3 to get 5. 
The numbers are simple enough to remember and then mentally add.
