This is a calculation printout from Hama Gakuen for 5th graders. Each sheet has points written on it. There are practice problems, and answers are included. Although numbered, some numbers are missing. There are a total of 42 sheets. The printout size is B4. There are no noticeable writings or stains. There are some folds and bends in the printouts. Please understand. How about using these for home study printouts? Thank you very much.
