Statistics is an area of Math that centers on data collection, presentation, and analysis. For example, the data from Sumdog.com Math Competitions show how Swift Middle School Homerooms' compare. Room 312 has set a goal of 55,000 points by 4-30, do you think that they'll reach their goal given the data shown below? The Math competition also shows room 313 in 1st place for the Fall Competition, will they be able to regain the lead in the Spring? Room 315 has set a goal of 30,000 points, is this goal attainable?

One popular game on Sumdog.com is "Junk Pile"- the game pictured on the logo above:) If you haven't tried out the games on this free web site, why not give it a try?!

### Compare the Surface Area

The area that covers the outside of a figure is its surface area. Surface area can be compared to wrapping a present or covering the outside of the object with paper.

The interactive tool at Annenbeg's web page shows how to find the surface area of cylinders and prisms. The surface area is the sum of 2 ends of the cylinder and the middle section.

Middle= Circumference * height + Ends (2 * Area)

Which container below has the greater surface area, and how much more area?

How would you verify and make sure that both containers have a volume of 750ml?
