Fraction strips are math manipulatives manufactured by Educational Insights to provide a multisensory approach to learning about fraction concepts and operations. The strips are designed to represent varying fraction amounts on pieces of foam.
According to Educational Insights, a complete set of fraction strips includes 51 pieces that represent fractions from 1/2 to 1/12.
