Deletion of Tsundue/Co-op Co-op

Comment: this article's title "Co-op Co-op" is the title of a book on Cooperative learning by Spencer Kagan. This article offers nothing that is not in the Cooperative learning article. The article appears to be promotional without the peacock words. The article is improperly titled being a sub-page of the non-existant "Tsundue". No redirect is appropriate. Kagan's book itself is not notable, fails . With no claim to importance or notability this might be an |A7 deletion, but a "learning strategy" is likely not "web content" or "organized event", and it is probably better to finish the Afd
