Cards, most readers are already familiar with them. There is one set of cards that no reader leaves home without. These are your charge, debit and/or credit cards that you will be using almost on a daily basis. The other cards with which some readers will be familiar with will be those that the guys scatter across the green felt mat during their weekly get together card games. Perhaps because most folks have the use of their eyes, they will not be familiar with braille cards nor will they have much use for it.
These learning cards are included in an interactive book of learning activities to help those who need to learn braille. Braille is the written language of the blind. Braille also needs to be learned by those who are not blind. Consider the parent who has a young child who is either born blind or has suddenly become blind owing to illness, disease or injurious accident. The concerned parent needs to learn how to communicate with his or her child.
The young child would also need lessons or help with his or her reading every once in a while in the absence of the specialist teacher. Learning cards are fabulous for a whole host of other purposes too. While on the subject of learning a foreign language, you might want to learn something new. It is not being taught in school and you might want to teach yourself at home. You might be able to learn French or Spanish easily enough over time because letters, words and vocabulary will become familiar to you.
But try learning Mandarin or Japanese. Or try learning Russian where you will first have to get to know the Cyrillic alphabet, or Gaelic even.
