Unit 12- 3D Shapes
This unit bundles student expectations that address identifying three-dimensional solids, identifying the two-dimensional components of three-dimensional objects, and
classifying and sorting two- and three-dimensional figures.
Prior to this unit, in Unit 10, students developed the prerequisite skills of sorting and classifying, and in Unit 11, students explored the attributes of two-dimensional shapes.
During this unit, students explore three-dimensional solids in the context of real world objects. Students use their knowledge of two-dimensional shapes to identify three-dimensional solids. Two-dimensional shapes found in real world objects are identified as components of three-dimensional solids. Students also classify and sort a collection of three-dimensional objects and a mixed collection of two- and three-dimensional figures based on their geometric attributes rather than other features such as orientation, color, texture, or size.
After this unit, students in Unit 14, students will apply their geometric knowledge as they explore the measurable attributes of objects.
Important notes!
They need to be exposed to lots of different examples of orientation. Things like size, texture, color, and orientation should not hinder them from being able to identify the figure and tell the 2D shapes that make up that figure.
