This one is just basically a waste of paper.  It doesn’t seem to have anything consistent about it.  I can’t tell what it’s purpose is.  It seems to be a book about finding shapes around us in our daily lives, but most of the text is random information about things that happen to be triangles, even though the information is irrelevant to the fact that they are triangles.  I guess it could be helpful to someone trying to learn English or Spanish, but there are better bilingual books for that.
