Polygons and Stars<\/strong><\/p>\n

Polygon basics: Based on Erfle, Wensel, Erfle and Polinka \u201cConnecting Geometric Patterns to Numeric Patterns using the Polygons and Stars<\/em> Excel File<\/a>,\u201d Spreadsheets in Education<\/em>, 2021.<\/p>\n

The link above takes you to a paper and Excel file (click here for the 1.Polygons and Stars<\/a> Excel file). This paper is targeted to K-2 and hence can be covered very quickly for those who are beyond these grades. There are two main sheets there, Polygons<\/em><\/strong> and Stars<\/em><\/strong>, together with supplementary sheets that are of interest mainly to teachers. The first sheet (Polygons<\/em><\/strong>) introduces users to n<\/em><\/strong>, the number of vertices<\/em> (and sides) in a regular polygon and the second sheet (Stars<\/em><\/strong>) introduces the notion of vertex jumps J<\/em><\/strong> which produce continuously drawn stars.<\/p>\n

E2. <\/strong>These explainers<\/em> (short documents) supplement the article above. Those denoted MA<\/strong> (for M<\/strong>athematical A<\/strong>pproach<\/em>) dive more deeply into the material and may not be accessible to primary school audiences.<\/p>\n
