Building strong Korean vocabulary has never been so exciting for preschoolers and toddlers. EFlashApps Korean Educational Baby Flash Cards features over 500 high quality images with text and voice-overs. There are additional real sounds where applicable (such as a lion's roar or an ambulance siren) to enhance visual and auditory learning and memory simultaneously. Parents have the option to turn voice-overs off during parent-child learning session and turn voice overs on when the child is self-learning. They can enable Question Mode to display 4 images and ask the child to click on the right answer. Complexity of words is perfect for ages 1 to 4 so two or more young siblings can play together and even teach each-other!
