After determining the areas of compound rectilinear shapes, learners share and evaluate each others' solutions.
These resources are part of KET's Math Instructional Strategies: Geometry collection.
While it is important that learners have guidance during their initial practice efforts with a new concept, sharing and evaluating others' solutions can also be instructive to both the teacher and the other learners. Often, an instructor can discover where a learner's thinking process has gone awry and ask the class for their thoughts on why this was an erroneous solution. Learners can observe that there are sometimes several ways to solve a problem that result in the correct answer. This can result in an appreciation of tolerance for others' opinions and judgment.
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.
