Narrative
Students lay six shape cards face up. One student picks two cards that have an attribute in common.  All students draw a shape that has a shared attribute with the two shapes. Students get a point if they draw a shape that no other student drew. It is possible that students will draw a shape with a different shared attribute than what the original student chose. This can be an interesting discussion for students to have.
Variation:
Students can choose a different shape card that matches, rather than draw a shape.
