Close your books and look at me.
Literal
Books [object-を] close-[sequential-て] me [object-を] look-[gentle-imperative-なさい].
Two sequential commands joined by the ~て form (used here as a connective linking actions). The second command is 見なさい ('look'). A typical classroom instruction pattern: the first action (close the book) precedes the second (look at me).
