Overview

The CyberSquad must build a path to cross a stream of hot lava. They find a pile of triangle-shaped tiles which float in the lava and don't melt. Unfortunately, they run out of triangle tiles when they are only halfway across the stream of lava and must figure out what other tiles they can use to complete the path.

Knowledge

Students know:
  • that shapesin different categories may share attributes and that the shared attributes can define a larger category.

Skills

Students are able to:
  • Identify two-dimensional shapes.
  • Sort shapes according to number of sides.
  • Sort quadrilaterals based on the presence or absence of square corners.
  • Draw examples of squares, rectangles, and rhombuses.
  • Draw quadrilaterals that are not rhombuses, rectangles, and squares.

Understanding

Students understand that:
  • Attributes of a shape help make decisions about how to categorize the shape.
  • Certain attributes are needed to belong to the subcategories of rhombuses, rectangles, and squares.
  • Sometimes a shape does not have the attributes needed to belong to the subcategories of rhombuses, rectangles, and squares.
