Unpacked Content
Knowledge
Students know:
- the difference between a two-dimensional and three-dimensional figure.
- The names and properties of two-dimensional shapes.
- The names and properties of three-dimensional solids.
Skills
Students are able to:
- discover two-dimensional shapes from slicing three-dimensional figures. For example, students might slice a clay rectangular prism from different perspectives to see what two-dimensional shapes occur from each slice.
Understanding
Students understand that:
- slices the prism from different planes may provide a different two-dimensional shape.
- There are specific two-dimensional shapes result from slicing a three-dimensional figure.
Vocabulary
- Two-dimensional figures
- Three-dimensional solids
- plane sections
