This was assigned long time ago, and I noticed that no one else is doing this. You guys, go to the spmathgr9 blog, and read Mr.Backe's post on October 4. Since we've learned most of this unit, you shouldn't be having much problems. But if you do, ask people, and ask Mr.Backe.
By the way, I'm really sorry that I can't really be able to comment on your posts right away. But I promise that I will when I get a chance.
I still need to answer all of these questions, but I published it right away, to remind all of you. Get it finished soon, and I'm sure Mr.Backe would be happy (:
