Begin building the foundation for future math success

The calculator can display two forms of fractional results simultaneously, allowing students to begin making crucial mathematic connections. Challenge them to manually simplify fractions and mixed numbers in traditional numerator/denominator format or enable the calculator to automatically simplify them or change them to decimal equivalents.

Engage students in self-directed problem-solving

Encourage students to explore math on their own with built-in flash cards that challenge their addition, subtraction, multiplication and division skills. Set the flash cards for the appropriate age and type of operation. The flash card functionality gives students hints when a wrong answer is entered and includes an internal scoreboard enabling teachers to check each student’s progress.
