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.

Learn to find the area of rectangles in this video. The instructor first reviews some basics about polygons and rectangles. In her first problem, she shows how to find the area of a rectangle by tiling it. She shows how tiling it and counting the squ...ares provides us with the same area as if we used multiplication. NOTE: She mistakenly says "triangles" instead of "rectangles" a couple of times when teaching the formula for area. In the second problem, she presents a word problem to find the area of a square.
