Eggsactly with Fractions
In this unit, students explore
relationships among fractions through work with the set model. This
early work with fraction relationships helps students make sense of
basic fraction concepts and facilitates work with comparing and ordering
fractions and working with equivalency.
Math Content
Students will:

Be exposed to the set model and be provided an opportunity to develop a thorough understanding of this model in multiple applications.
 In the set model, the unit is represented by the entire set, and
subsets of
the unit make up the fractional parts. For example, in a set of 12 eggs,
4 eggs comprise onethird of the set of 16 eggs. The set of 12 in this
example represents the whole, or 1.
 This notion of referring to a collection of objects makes studying the set
model difficult for young children. As students work with a variety of fraction
models in contexts that promote reasoning and problem solving, they develop a
more thorough understanding of fractions and their relationships.

Students begin to examine fractions as part of a set. This lesson helps students develop skill in problem solving and reasoning as they examine relationships among the fractions used to describe part of a set of 12.

Students continue to examine fractions as part of a set. This lesson helps students develop skill in problem solving and reasoning as they examine relationships among the fractions used to describe part of a set of eighteen.

Students use twelve eggs to identify equivalent fractions. Construction paper cutouts are used as a physical model to represent various fractions of the set of eggs, for example, 1/12, 1/6, and 1/3. Students investigate relationships among fractions that are equivalent.

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.

During this lesson, students create their own classroom survey or use previously generated questions to study the class and describe the set [class] in fractional parts. This lesson requires that students identify fractions in realworld contexts from a set of items that are not identical. This lesson is integrated with other areas of the math curriculum, including data analysis and statistics.

This lesson gives students another opportunity to explore fractions using the set model. This lesson is integrated with other areas of the math curriculum including data analysis and statistics.
