KUMON Subtraction Practice Includes "Well Done! Stickers" and a "Great Job! Certificate" 78 pages total (38 sheets) Some pages have writing that has been erased, and some pages have writing that remains. However, more than half are blank, so I am listing this for sale. Pages with colored pencil markings have been left as is and not erased. Of the erased pages, some have been erased relatively cleanly, while others still have strong pressure marks. Pages 1-2 = Missing Pages 3-7, 18 = Writing not erased Pages 8-17, 19-30 = Writing erased Pages 31-78 = Blank Only one "Well Done!" sticker is creased.
