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. ===== Core Features ===== Flashcard-style interface that sparks enthusiasm and deepens understanding of arithmetic operations Customizable drills: 2- or 3-digit addition, subtraction, multiplication, and division within ranges of 10, 20, 30, 50, or 100 — perfect for preschoolers and elementary students Clear progress insights: Track speed, accuracy, and fluency to understand your child’s mastery of each operation Motivational rewards: Levels, medals, and badges encourage consistent practice and build confidence ===== Premium Subscription Options ===== All subscriptions are non-renewing: - 7-day free trial (no auto-renewal after trial) - 1-month access (non-renewing) - 12-month access (non-renewing) - Lifetime access (one-time purchase, forever) Subscription prices are displayed in the app at the time of purchase.
