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.
