The Croco flashcard box impresses with a learning system that is as simple as it is effective: acquired knowledge is regularly recalled and thus stored for the long term. The vocabulary cards are regularly learnt and repeated according to the 5-subject learning method. Around 20-30 new vocabulary items are placed in the first compartment and learnt - vocabulary items that have been learnt are moved to the second compartment, while those that have not been learnt remain in the first. The same happens the next day with the cards from tray 2. The aim is to place the cards in tray 5 and to have them stored in the long-term memory by then. Ideal for learning basic vocabulary as well as learning material such as formulae, grammar and much more. A learning aid for young and old - the practical Croco flashcard box.
