**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.
