SBM 1000 Lecture 5: math on geo
Document Summary
Education agency, mathematical process standards including application, tools and techniques, representations, relationships, and justifications should be integrated (when applicable) with content knowledge and skills so that students are prepared to use mathematics in everyday life, society, and the workplace. Prior to this unit, in grade 2, students analyzed attributes of two-dimensional shapes and three-dimensional solids in order to develop generalizations about their properties. Using formal geometric language, students classified and sorted polygons with 12 or fewer sides by identifying the number of sides and number of vertices. During this unit, students continue to develop their understanding of geometric figures by sorting and classifying two- and three-dimensional figures that may vary in size, shape, and orientation based on attributes using formal geometric language. Students focus their exploration of two-dimensional figures as they explore subcategories of quadrilaterals, including rhombuses, parallelograms, trapezoids, rectangles, and squares.
