This is a set of math problem books and answer keys for 5th graders. - Title: New Practice for Junior High School Entrance Exams: Math, Grade 5, Part 2 (Lower Volume) - Title: New Practice for Junior High School Entrance Exams: Math, Grade 5, Part 2 (Lower Volume) - Answers and Explanations - Contents: Math problem book and its answers/explanations - Volume: Lower Volume - Target Grade: 5th Grade Elementary School There are about 45 pages with writing out of 204 pages, but it's mostly doodles or minor problem-solving attempts, so the problem book can still be used for the most part. There are a few tears, but I think it's okay. Please refer to the photos. Thank you for looking.
