1st Grade Review Quiz Master 100 Benesse Shinken Zemi Elementary School 1st Grade Math, Japanese Language Arts, Educational Material This is an educational material where you insert cards into the main unit and answer quizzes. When you press the button with the number you think is the correct answer, Korasho will tell you whether it's correct or incorrect with his voice, and you can earn star points, making learning fun. You can do 120 questions in Japanese Language Arts and Math that are learned in the 1st grade. There are 60 cards in total, as the questions are on both sides. All cards are present, but some may not insert properly due to tears or folds. Many cards are curled and difficult to insert. Please be aware of this. There is no instruction manual, but the operation is simple, so I think you can use it without any problems. Batteries are not included. Uses 2 AAA batteries. Please purchase if you understand that this is a used item with tears, folds, and stains.
