This series of videos was created to help middle school and early high school students understand the concepts and math of perimeter, area, and volume and how they can be used in a real life situation  in this case, a brother and sister want to buil...d a new dog pen for their new puppy. This series of videos was created to be colorful, animated, and funny, so that students will want to watch the videos. This video concentrates on finding the perimeter of the new dog pen, so the brother and sister know how much fencing to buy. There is a cartoon of the brother and sister, and then along with it, there are animations that explain the concept of perimeter, and work through the math needed to figure out how much fencing they need to buy. The voices are computer generated, and may be annoying to some, but kids in this age group tend to find them amusing.

In this Cyberchase video segment, Matt and Jackie must figure out how to construct rectangular lids that match the size of two boxes precisely. They enlist the carpentry skills of one of the Three Little Pigs, who shows them how to use different tool...s to accurately measure the rectangular lids. For the first box, Jackie finds that she can easily trace the box to make a lid that fits perfectly. The second box cannot be traced, so Matt and Jackie decide to measure the sides of the box and then use the measurements to cut a rectangle of equal size out of a piece of Herculanium. (4:11)
