I love this lesson plan which includes algebra, ratios, angles, and stastics that most 9th and 10th graders I know could compute. This could be a very fund summary activity. Look at this PDF and powerpoint and create your own. If you do, please share it with me in the comments or email it to me, I'd like to share what you do.
