Hi,
Does anyone have a good game for teaching/reinforcing rounding? I’m a new ld resource teacher trying to think of appropriate but fun ways to teach and review math concepts in a small group. I really appreciate any ideas or advice.
Thanks!
Re: rounding
If you have a computer in your room, you might want to consider Quarter Mile Math. Website is http://www.thequartermile.com . You can email or call them for a demo CD. Unfortunately, this is not a group activity (which I assume is what you are looking for).

Re: rounding
I have an activity idea, which I got from my own life. I have become really awesome at estimating how much my groceries are going to cost before I get to check out. What I do is this: if it is under $.50 (actually for real life sake it works better if you do $.45) you drop it and if it is over that it becomes $1. What you could do is this: get a bunch of those colorful pictures from the grocery store flyers (I must get 10 of these a week). Stick them on 3X5 cards and have pass out a number to each kid.
If there is no price on them you can write one in in felt tip.
Or if it is so much a pound they just have a pound.
They take a few of these and estimate their grocery bill. Then they check it out carefully and see how close they get. It is a useful life skill.

I don’t do games, sorry.
But please be sure whatever way you approach this that you teach the number line and look for the *nearest* — that’s the big picture concept that is vital.
I have a student right now, Grade 7, who has been taught all sorts of tricks with number symbols, which he is not too good with because they don’t mean anything to him; I was using number lines for tenths and hundredths and rounding both decimals and large whole numbers, and lo and behold, he didn’t know how to draw a number line using tenths, or groups of tens and hundreds — funny how he can’t do meaningful work with decimals when he doesn’t even have a mental model for them.
