I need this answer by Monday, April, 14, 2008. I need it for a social project I am doing and I can't find it anywhere!! So can someone plzzzz answer this for me it would be a great help!!

I have no idea if there is even any accurate number on this here are some search sites
AOL Search results for "number of children in China sweatshops"

I normally don't help with homework but this is hard at best.

First there is no real count. So any number is just a guess.
And what is slave labor or sweat shops to one group may not be to antoher. Some civil rights group calls some of the work done by teens in the US are consider child labor to them.

But this web site
Child Labor Throuhghout the world

Says that there are about 250 million children in slave labor and sweat shops. And about 60 percent of them are in China.

Then there is also the following search that one might want to click on and see what information might be on some of the sites listed.
