This virtual manipulative from NCTM Illuminations uses area (circles,squares) and linear measure representations.
Fractions - Equivalent
This is an interactive activity from NLVM in which you are given an area representation of a fraction and you are asked to create and name an equivalent fraction.
Fractions - Naming
This is an interactive activity from NLVM in which you are given an area representation of a fraction and you are asked to name the fraction.
Fractions - Comparing
This is an interactive activity from NLVM that uses a common denominator strategy for comparing two fractions.
Fractions - Visualizing
This is an interactive activity from NLVM in which you are given a numeric representation then asked to create an area representation.
Equivalent Fraction Rings
This is an interactive activity in which you practice making equivalent fractions using a fraction ring.

, Student Achievement Effects of Technology-Supported Remediation of Understanding of Fractions
Students have difficulty learning fractions and problems in understanding fractions persist into adulthood, with moderate to severe consequences for everyday and occupational decision making. Remediation of student misconceptions is hampered by deficiencies in teachers’ knowledge of the discipline and pedagogical content knowledge. We theorized that a technology
resource could provide the sequencing and scaffolding that teachers might have difficulty providing. Five sets of learning objects, called CLIPS, were developed to provide remediation on fraction concepts.
