In this interactive activity adapted from the Wisconsin Online Resource Center, use mathematics and measuring skills to solve a construction problem. Play a game using tools (including a tape measure, notepad, and calculator) to determine how many sh...ingles are needed to reroof a house. Learn about the importance of proper planning and how miscalculating the amount of materials needed can add to the cost and time spent on a project.

Dunk Tank is a maththemed game show created by the producers of Cyberchase and starring Harry from Cyberchase For Real. Using a combination of video and interactive gaming, each program addresses a single topic in the 6th grade math curriculum and s...tudents compete with themselves for high scores. Dunk Tank is an independent learning experience for students to complete in 1530 minutes, depending on their proficiency, and can also be used to support teacherled instruction. In this interactive, Harry explains key concepts about finding the area of squares, rectangles and composite shapes, including measuring with unit squares and using the formula Length x Width to calculate area. Students play Polygonathon, a minigame that challenges them to make simple polygons and find their areas; watch a comic video about using a nonstandard unit of measure – sleeping bags! – to calculate how many friends can come for a sleepover; and answer other questions designed to help them further their understanding of area. Students can access support using a glossary, defining key math terms, and a menu of short segments to rewatch.

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.
