7th grade - Extra activity for extra credit
The following is for you to practice at home. It is not mandatory. However, if you wish for me to correct your work and go after some extrra credit, make sure you copy these exercises, paste them in a word document and print it out. To apply for the extra credit, I would need to have this worksheet befor Jan. 20th, 2012.
Enjoy!
