When working on basic subtraction, my DS 9, still uses a number line for subtraction. I'm not sure how long he should continue using this. He def. has a problem with retaining information so learning the math facts is quite a struggle. He seems to "get it" one day and then forget. Any advice?
TIA,

Could you "wean" him from it? ask him to try without it first and then check with the number line?

My experience has been that children will use manipulatives as long as they are helpful. Once they learn enough that using the manipulative actually slows them down, they will wean themselves.

I was just reading Ruth Beechick's math book last night, and she says that children will naturally give up manipulatives when they are ready- as Theresa says, they will stop using them when their mental math is faster than using the manipulative. So my hunch would be to let him use it till he's ready to give it up on his own. But I don't have a 9 year old, so take that with a grain of salt.

We are using a number line with MEP math right now. One of the exercises is to find the next nearest numbers of a specific number, then the next nearest ten on either side of the number. Another part of the exercise is to notice if the next nearest numbers to a specific number are odd or even. Once they see that a number is odd, they will see that the next nearest numbers are even, and vice versa.
I'm saying all of that to show that it's okay to let that number line stick around for awhile. This might even be a fun activity to try with him.
I agree that kids will wean themselves from manipulatives. My child tells me many times when I've offered different things to use that he doesn't need them. But he has had his share of time with them up until this point.

Sorry about not including the link. It's a program from the UK that's based on a Hungarian math program.
http://www.cimt.plymouth.ac.uk/projects/mep/default.htm
We love this program, and it's been working well for us. We do move slowly through though, and spend extra time on some concepts such as time and measurement. It's free, except for your ink and paper to print. I found copy paper at Walmart during their back-to-school supply sale for $2.50 a ream. I also refill my own ink cartridges, so that is ink cost is not a factor for me. When Big Lots has their 20% off coupons I try to buy several refill kits for ~$5 or so. These last me a long time.
The MEP website has a number line that you can print off and cut out and laminate or just cover with clear contact paper. You'd have to tape the ends together for each 10, but then it's expandable. Or you could make your own durable number line with a piece of poster board cut in strips of 10 and taped together.
