Ideas?

Does anyone have any ideas on where I could find a really good Problem Based Learning curriculum for my gifted 6th grade math students? The GT curriculum we have right now is difficult to work with and I am getting frustrated, as are my students! HELP!

I'm teaching them how...

The students in my GT Academy don't know it but the units of instruction I have been given for them just aren't really cutting the mustard. SO, the Media Specialist at my school made some recommendations for what we could do rather than me pulling my hair out and the kids hating me before the end of school. I'm not telling all of her ideas, because that would give it all away, but one of them was to teach the kids to create a blog or wiki, so I'm showing them on my Promethean Board how to do all this. They're sitting in the room, reading out loud, sounding quite ridiculous, but that is the life of a middle schooler, right? So I typed the first paragraph (above), then saved and showed them how to edit. TA DAAAAAAAAAAAA!
