Fraction strips are math manipulatives manufactured by Educational Insights to provide a multi-sensory approach to learning about fraction concepts and operations. The strips are designed to represent varying fraction amounts on pieces of foam.
Continue ReadingAccording to Educational Insights, a complete set of fraction strips includes 51 pieces that represent fractions from 1/2 to 1/12. A set also includes a strip to represent the concept of one whole unit. The magnetic qualities of the manipulatives make it possible to display them on white boards or other magnetic surfaces for lessons. Students are able to visualize the relationships between various fractional amounts. They can also model operations with fractions as they use the color-coded strips.
