## Card Maths Description
Why Mental Math Matters for Kids

- Mental arithmetic is an essential part of early math education.
- A child’s calculation speed and accuracy directly reflect their mental math skills—and ultimately influence their overall math performance.
- Young learners often struggle with focus and lack clear goals. The key to improving learning quality lies in sparking interest and boosting motivation.
- Practicing math with flashcards feels like play to children, reduces mental fatigue, and is a proven, effective method for early math development.

Card Maths is a fast-calculation practice app for kids, thoughtfully designed around these principles.
