Most of them are Shichida Method flashcards. Since they attended Shichida Child Academy and Heguru, they did flashcards every day. I was half-skeptical about whether memory and thinking speed would really improve, but I think my child's memory and calculation skills have improved considerably. I made handmade cards by cutting out the worksheets distributed at Heguru, and made Thomas flashcards, devising ways to keep them from getting bored. They are no longer in use, so I will give them to anyone interested in their child's intellectual development. Since they were used by my child, there may be some signs of use and some missing cards, so please understand before purchasing. - Item Type: Card Game - Theme: Animals, Vehicles, Vegetables - Language: Japanese, English - Character: Thomas and Friends - Quantity: Numerous - Number Cards: 50 - Visual Elements: Illustrated - Educational Elements: For intellectual development Thank you for looking.
