For early language arts students, this classroom activity helps students with spelling, parts of speech and synonym and antonym identification.  The teacher should prepare a lengthy list of searchable items that can be found in the room (something spelled with double vowels, something shaped like an antonym for "flat," a blue-colored noun, etc).  Break students into teams and assign them either the complete list or a portion.  Give them time to identify all the things on the list, and finish the activity by comparing lists as a large group.
