Math workbook for first graders, with a scholastic ability diagnostic test. I believe I've erased all pencil markings. There is only one page with problem-solving marks, and the rest only have date records. There may be oversights. I've included a photo of the erased page. There is quite a bit of scribbling on the back of the answer key, but it shouldn't affect problem-solving. I'm aiming to offer it at a low price, so please refrain from purchasing if you are concerned about the condition. - Title: Top Class Problem Collection for Aiming for Junior High School Entrance Exams, Math, Grade 1 Revised Edition - ISBN: 978-4-581-00464-4 - Price: 1300 yen - Contents: Math workbook with a scholastic ability diagnostic test Thank you for looking.
