What is StudyX MathCal?
StudyX MathCal is a math practice app for iPhone and iPad where kids write their answers by hand. Fast handwritten calculation drills build the mental math skills that form the foundation of elementary and junior high math, and they make good daily brain training, too.
Beyond the drills, 59 interactive Montessori lessons use beads to show how arithmetic really works, from fractions and decimals to geometry and measurement. Three daily picks are free every day: Today's Drill, Today's Challenge, and Today's Lesson. A calendar stamp marks each finished session so progress is easy to see. The app is ad-free, works offline, and is designed so children can use it safely on their own.
