    As many of the people responding to this post, I was struck by the more vs. less language as well. I have often wondered why thinking through subtraction and division was alway harder for students than adding or multiplying. This is much clearer for me now.

    Students might compare quantities of stickers or erasers by lining them up with 1-1 correspondences. Actually this reminds me of how my mom and I count the score when we play “Ticket to Ride”. We compare similar trains so we only have to count the ones that are left over. I don’t know if this is an exact example using mathematical strategies, but it reminds me of that! Perhaps we need to move beyond comparison and use another strategy… 😉
