The Casio fx-55PLUS is a specialized calculator designed to support elementary and middle school students in learning fraction arithmetic. The device features a "Simplify" button that allows students to reduce fractions step-by-step, helping to monitor their understanding of the process. It is constructed from high-impact ABS plastic, built to withstand a standard drop from a school desk.
This model uses a "Natural Textbook Display" on a high-contrast dot-matrix LCD panel, which helps maintain legibility under standard overhead classroom lighting. It features a dual power system, utilizing both solar energy and an internal battery. The keys are rubberized to provide a tactile feel and help prevent accidental inputs during the learning process.
Educational Features
- True fraction logic handles mixed numbers and improper fractions exactly as they appear in books.
- Pedagogical tools help students visualize the steps of mathematical simplification.
- High-efficiency solar panel ensures the device is ready for use in typical home or classroom light.
The included hard slide-on case is a helpful feature for protecting the screen from scratches caused by pencils or other tools in a backpack. While this model is highly effective for grades 3 through 7, it is designed as a foundational tool rather than a long-term scientific solution. Storing the device at room temperature helps maintain the flexibility of the plastic case over time.
When students are ready for high school trigonometry and algebra, the Casio fx-300ES Plus is a suitable next step.
