Finding the area of geometric shapes requires being familiar with their respective formulas, as each type of shape involves different methods and equations. The instructor uses a document camera to model examples.

In math, different equations are needed to find the areas of different geometric shapes. Find the area of geometric shapes with tips from a math teacher

In this video segment from Cyberchase, the CyberSquad must compare two parcels of land during a land rush. One parcel is an irregular shape and belongs to Hacker. The other parcel is a regular rectangle and belongs to Judge Trudy. By dividing each pa...rcel into squares and triangles, they prove that the two shapes have the same area. (2:30)[more]

Dunk Tank is a math-themed 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 15-30 minutes, depending on their proficiency, and can also be used to support teacher-led 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 Polygon-athon, a mini-game that challenges them to make simple polygons and find their areas; watch a comic video about using a non-standard 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 re-watch.[more]

In this video segment from Cyberchase, the CyberSquad must measure two differently-shaped parcels of land to determine which has a larger area. The CyberSquad uses tarps, fence posts, and finally a grid made out of rope to count squares and determine... the area of each parcel. (3:54)[more]

In this video TenMarks teaches you how to compute area of triangles and trapezoids. The instructor uses computer software for demonstration. There is a lot of information on the screen, so the viewer may wish to open the video to 'full screen'.(04:21...)[more]

To measure the area of a given shape, a general rule of thumb is to multiply the length by the width and use square units to express the resulting value. The instructor uses a document camera to demonstrate this concept. (02:37)

The instructor demonstrates how to find the area of complex figures consisting of one or more rectangles. They show how to break the figure up into two different figures and then add the areas together. The first figure is in the perimeter video, s...o to find the missing sides you could watch that video or just go on in this video and they give you the measurements. They discuss the formula for area of a square and rectangle and use this to find the area of the two figures and then add them together. They also discuss why the area is label as cm squared or inches squared. Then other examples are shown. Video is good quality and good for all students as review or initial learning of the concept.[more]
