Subject: Re: Subtraction

Have you tried letting them use counters to do what you are describing to them? Perhaps, it is just too difficult for some of your students to visualize what you are saying. Get a handful of counters and let them begin with the 8 and count up to 13. Have them explore with the counters to find other subtraction problems like that one that also have a difference of 5. If they organize the problems from least to greatest "top number" or minuend, they should notice something interesting. I would be interested in hearing if using the counters helps them figure out what you are trying to help them see. -Gail, for the Teacher2Teacher service
