This is educational material from "Challenge 1st Grade." The main focus is "Science" since the main book has been used. Other items include educational toys, etc. (Some items have been listed separately, so the photos show everything included) I have erased any parts where the child made markings. I believe there are no other writings, but there might be some oversight. I also sell other educational materials from Challenge 1st and 2nd grade. If you purchase multiple items, I can offer a discount on shipping, so please contact me before purchasing. *Please note that I do not ship on weekends and holidays. *I may change the shipping method between Yu-Yu Mercari and Raku-Raku Mercari.
