Learners are asked to use their method of preference; counting unit squares or multiplying length by width to find the area of rectangles.
These resources are part of KET's Math Instructional Strategies: Geometry collection.
Learning something new usually involves moving from concrete thought processes to more abstract ones. When learning about finding the area of plane figures, learners may move from a concrete process, i.e. counting unit squares, to a more abstract one such as multiplying dimensions. Oftentimes some type of graphic representation assists for both concrete and abstract methods. Learners should be encouraged to draw representations of problems to help them in their solution.
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
