Sixth Grade Math Textbook Workbook from Tokyo Shoseki Current edition. This is the new edition released last year, so it was purchased a year ago. There are no markings in the workbook. An answer booklet is also included. Of the four tear-out tests, two have been torn out, and one has writing on half of it. The cover and the book are taped together. Please check the photos. Instant purchase is OK. No pets, no smokers!
