Listen to ONGO's original music tracks with your child. Music activates the brain's reward circuits, boosting motivation, and idioms set to melody are remembered longer.

3. Build a Daily Brain Exercise Habit

Build a habit of solving 5 daily questions in ONGO Brain Exercise. Just 3 minutes, but Active Recall training significantly improves retention.
