Narrative
Students lay six shape cards face up. One student picks two cards that have an attribute in common. All students write an attribute that is shared by both shapes. Students get a point if they name an attribute that no other student wrote.
Variation:
Students can draw a shape that has a shared attribute with the given shapes.
