Created by math teacher Jeff LeMieux, the Fractionator offers hands-on tools to help students develop an understanding of fractions. The online tools model two fractions to be added (or subtracted) based on unit squares and then creates equivalent fraction models, allowing students to solve the problem. Two of the online demonstrations show a unique problem each time a new problem is requested, while a third tool allows students themselves to enter the two fractions. Also provided are links to printable materials, such as overhead transparencies and student worksheets.

Description	The Middle School Portal 2: Math and Science Pathways (MSP2) supports middle grades educators with high-quality, standards-based resources and promotes collaboration and knowledge-sharing among its users. Educators use MSP2 to increase content knowledge in science, mathematics, and appropriate pedagogy for youth ages 10 to 15. MSP2 employs social networking and digital tools to foster dynamic experiences that promote creation, modification, and sharing of resources, facilitate professional development, and support the integration of technology into practice. MSP2 is a project of the Ohio State University College of Education and Human Ecology, National Middle School Association, and Education Development Center, Inc., and is funded by the National Science Foundation. The partners integrate resources, tools, and services across projects, and support multiple methods of resource discovery to meet the needs of this audience.

  The Fractionator The Fractionator is one result of an ongoing effort to find hands-on tools for students to develop understanding of fractions. The purpose of the Fractionator is to draw and divide unit squares to model or represent fractions and then to create equivalent fractions allowing the student to solve the addition (or subtraction) problem. The Really Short Fractionator Tutorial Fractionator Materials: �Overheads (Word© Document) Print two sets on transparencies. Overhead Sets This will allow a demonstration modelling the first fraction and overlaying the grid for the second fraction (at right angles) to demonstrate the equivalent form. �The Fractionator (GIF). Download this file and using either a graphics program or Word© (or similar), print out on card stock - have students cut out their own copy. The Fractionator Tools: The demonstrations show a unique problem each time the script is called. New problems can be displayed with a click. The addition tool allows the student to enter their specific proper fraction addition problem.
