This is a Benesse Shinkenzemi Elementary School Course book. It covers the kanji learned in 6th grade (as of 2015), including their structure, example sentences, and proverbs, presented in a manga and dictionary format. It's fun just to read! It was a supplement to "Challenge," so there are some references to "Challenge," but you can still enjoy it without them. Please review the photos before purchasing. Understand that this is a used item stored at home, and we appreciate your purchase.
