(21 sheets missing: 118 and 181-200) ② 12 sheets have been written on, but erased with an eraser. Faint traces of writing are visible. (See photos) 14 sheets are blank. Total: 26 sheets. * Written on and graded. * Names, answers, dates, and times are as they are. * The missing sheets from 181-200 are not included because the teacher allowed my child to skip them as they were ahead in their studies and took the final test without them. One sheet is missing. These are worksheets used by a child, so there may be folds, stains, and tears. The handwriting is also messy. I have taken photos of any particularly noticeable areas. (See photos) I have checked the number of sheets, but please forgive any missing or duplicate sheets. Please purchase only if you understand the condition of the product. Returns are not accepted as the material can be copied. Thank you for your understanding.
