This is a calculation worksheet from Hama Gakuen for 5th graders. Each sheet has points and other notes written on it. The sheets are numbered, but some numbers are missing. There are a total of 42 sheets. The size of the worksheets is B4. There are no noticeable writings or stains, but there are some folds and bends in the sheets. Please understand. Would you like to use these for home study worksheets, etc.? Thank you very much.
