Texas Instruments TEXTI15 Elementary Calculator Dual Power

Product Description

The Texas Instruments TEXTI15 is an elementary calculator built for classroom use in grades 3 through 6. It features a two-line display that shows 11 digits per line, allowing students to see both their input and results simultaneously. The calculator handles fractions, decimals, and percents, and follows M-D-A-S order of operations automatically. It simplifies fractions either automatically or step-by-step, and converts between improper fractions, mixed numbers, decimals, and percents. Dual power operation runs on both battery and solar, reducing the chance of a dead unit mid-class. An impact-resistant cover and hard plastic color-coded keys are built to hold up in a school environment.

This calculator is designed for elementary school settings where students are developing foundational math skills in fractions, decimals, and basic operations. It is suited for classroom assignments, homework, and math drills in grades 3 through 6. The built-in flash card function covers addition, subtraction, multiplication, and division, complete with hints and an internal scoreboard, making it useful for timed practice and skills reinforcement alongside standard curriculum instruction.
