From: Leeann Wieser <firstname.lastname@example.org> To: Teacher2Teacher Public Discussion Date: 1999082600:11:16 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.
