Investigating Fraction Relationships with Relationship Rods

In this lesson plan from Illuminations, students use relationship rods to explore fraction relationships. Relationship rods range in length from one to ten centimeters, and each rod is a different color. An activity sheet with solutions, questions for students, assessment options, and suggested extension activities are included. The lesson plan is part of a five lesson plan unit, Fun with Fractions, which is cataloged separately.

Getting Off to a Good Start with FractionsThis collection is the first of a series that addresses the importance of helping students to construct a solid foundation for fractions. Unit fraction, equal shares, partitioning and iterating, identifying and making wholes are presented as appropriate concepts to begin instruction. Resources include several studies with recommendations for best practices and teaching strategies, as well as some virtual manipulatives to aid implementation. The collection also supports specialists and teachers as they explore ways to address common difficulties and misconceptions.

      Great hands-on investigation

    • This is a great hands-on investigation. I love how students not only make parts of a whole but also make mixed numbers depending on which rod equals a whole.
