Illuminations: Another Look at the Set Model using Attribute Pieces

The previous lessons focused on the set model where all objects in the set are the same size and shape.

Students also need work with sets in which the objects “look” different. In the real world, we are often faced with fraction situations where the objects in the set are not identical. For this lesson, students use fractions to describe a set of attribute pieces. Students develop skill in problem solving and reasoning as they think about their set and how to create new sets given specific fractional characteristics.
