"Crossword Puzzles for 1st and 2nd Graders: Mastering Important Vocabulary!" Ochanomizu University Elementary School Price: ¥900 Used up to the first 5 pages. The rest is blank. I took it with me on trips and outings. I think it's a book that parents and children can enjoy while learning. My child used it. Please refrain from purchasing if you are concerned about minor details. #OchanomizuUniversityElementarySchool #Books #Language/General"
