Finger Numbers is a motivating learning app that builds rapid quantity recognition (quasi‑simultaneous subitizing) and a robust sense of number and operations for early math. This release is a complete technical rebuild with expanded content—designed for children, parents, and teachers. What children practice: - Recognizing quantities at a glance and matching them with finger touches - Automating number decompositions, complements to 10, and strategies like the “Power of 5” - Moving fluently between representations (fingers, dots, mixed) Game and practice modes: - Basics: Fingers, Dots, Mixed - Pattern Recognition: structured arrangements - Calculation Strategies: Power of 5, complements to 10, How many are missing?, decompositions - Two Hands: cooperative/competitive split‑screen number decomposition - Jump and Run: an action mini‑game controlled by finger numbers Adapt to each learner: - Flexible number range from 3 to 10 fingers (start with 3-5 Fingers for learning the input) - Time pressure can be enabled/disabled as needed - Visual aids and flash‑view controls - Multi‑user profiles with individual progress; Guest mode without recording For teachers - Diagnostic reports with solution times, success rates, and strategy insights - Protected area to review learning progress - AI‑powered summaries with didactic guidance Note: On iPad, system gestures (e.g., 4–5‑finger gestures) may interfere with multi‑finger input. Consider disabling multitasking gestures in system settings if needed. Languages: German, English, Spanish, French, Japanese, Chinese (Simplified)
