Composing Two-Dimensional Shapes & Three-Dimensional Solids Based on Attributes or Properties
T.I.P.S.
Students must be able to combine smaller shapes or solids to compose larger shapes or solids that have the properties and attributes that are given such as the number of sides or vertices. Students could build these figures using color tiles, tangram shapes, centimeter cubes, pattern blocks, and linking cubes as well as with a pencil and paper.
Example
Use words and drawings to compose larger polygons with smaller polygons and explain your thinking.
a) Which polygons could be used compose a quadrilateral with 4 square corners? b) Which polygons could be used to compose a rectangle? c) Using 8 color tiles or squares, how many quadrilaterals could you build?

2.8 Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to: (D) compose two-dimensional shapes and three-dimensional solids with given properties or attributesFeedback
