See, Touch, Listen & Learn. Learning is enhanced when multiple senses are engaged! With Link4fun Flashcards, kids use physical flashcards to enrich their iPad experience and to learn beyond the screen. Research shows that when more sensory activities are involved, lessons are better absorbed and more neural pathways are formed. With the Link4fun Foods Master-pack of Flashcards, kids are: grasping and tapping the cards for larger motor movement scanning left and right across the physical cards spread-out in front of them listening to the words from the iPad looking at the colorful pictures reading new site-words. The master-pack includes 72 Link4fun Cards, 36 picture cards and 36 word cards, as well as the free iPad app with 8 different learning activities that teach picture matching, word matching, site reading and new vocabulary. Set includes: Fruits Vegetables Dairy Protein Grains Snacks Curious how we make the magic happen? Each card is printed on the reverse with a special invisible ink (no really!). The pattern created by the ink ‘tricks’ the ipad into thinking that it is recognizing a pattern that you drew with your fingers, allowing the app to recognize and react to the printed flashcard. This is a revolutionary technology that is not being used ANYWERE else in education.
