This is a Sumikko Gurashi learning drill. For children in 4th grade who struggle with units and geometry (о´∀`о) The text itself has no noticeable scratches or stains. There are about 5 pages with random writing in the first half, but the pencil marks have been erased. Please forgive any remaining marks that may have been missed. Please note that there are a few remaining markings and circled answers in red ballpoint pen. About 4 stickers have been used, but most of them remain.
