This is a text for second graders from the "Challenge" program. It has been stored at home as the child did not use it, so I am putting it up for sale. It is the September, October, November, and December issues of 2022. It contains Japanese language and math problems that are learned around September to December of the second grade. The problems for the "Red Pen Teacher" have been cut out and completed, but the contents are unused. Although unused, there are minor scratches on the cover due to home storage, so thank you for your understanding. #Challenge #ElementaryCourse #SecondGrade #ShinkenZemi
