This is a set of educational materials for the second half of 5th grade to 6th grade. Some of the problems had already been solved by the child, so those pages have been discarded. I think it would be good to use these to supplement studies during spring break and winter break. ① Juken Research Co., Ltd. Kanji Training A training book to learn the basics of kanji with one page per day. This is new and has not been written in. ② Challenge 6th Grade Math: 9 pages Science: 1 page Social Studies: 4 pages Social Studies + Science: 4 pages Japanese: 6 pages Answer booklet included. The condition is not very good. ③ Diamond Inc. The book that allows elementary school students to perfectly do mental calculations in just one day. Only about 10 pages left. I think it would be good to use this to review calculations. Items ② and ③ are used. Please refrain from purchasing if you are concerned about the condition. Thank you for looking.
