The others ask questions about its properties, trying to guess it. Investigate and predict the results of combining, subdividing, and changing shapes. Students investigate the shapes found in their lunches and then discuss how the shapes change as they nibble away. Students combine tangram pieces to create a variety of shapes. Use tessellations to explore properties of geometric shapes and their relationships to the concepts of area and perimeter.
Students use square, triangular, and hexagonal grid paper to create colorful designs.
They discuss why these polygon shapes fit together like a puzzle. Students use Unifix cubes or pattern blocks to create designs. Students work through the Tiling a Floor lesson that is described in the First FourStandards of this Framework . They discover that the shapes which can be used for tiling must be able to fit around a point without leaving spaces and without overlapping. Students create borders from a single simple design element which is repeated using slides, flips, and turns.
