Marylou had a great suggestion for you when she mentioned the number line. That is what I used to use with fourth graders (and now use with some fifth graders) who have trouble picturing the process. I am assuming you are rounding to the greatest place value each time. That is probably the place you should stay until your student is very comfortable with that ( in other words, don't try going on to rounding a four digit number to the nearest hundred, etc.) The best thing about the number line is that it gives students a mental image they can access whenever they need it. Finding the number on the line, and noting which "ten" or "hundred" is closer is much easier because it gives them something a little more concrete to base their decision on. -Gail, for the Teacher2Teacher service
