Hi! Sorry it took so long, to reply to this (I've been in the process of moving), I can definitely help with this one!
noun -- a person (point to yourself), a place (point somewhere in the room), a thing (make big gnarly hands and hunch over like a hideous 'thing'), or an idea (make a lightbulb 'ding' over your head with your hands)
action verb-- an action or something you do (make running arms or some other active gesture)
helping verb -- (link your hands together)
adjective -- modifies a noun (flip your hair and glance in a mirror like you're beautifying yourself)
adverb -- modifies a verb, tells you how (shrug shoulders and look very puzzled), when (point to your watch), or where (shade your eyes like you're looking in the distance)
subject and predicate-- these go together, and my students learn the gestures and their position as parts of a sentence... you need two hands. subject comes first--put your fist out in front of you to the students' left (it's easier for them to mirror you if you do things oppposite...so I use my right hand and it goes to my right, their left)-- predicate comes last -- put your fist out in front of you to your students' right, next to the subject fist.
Then put them together to make a complete sentence. If you use it enough, your students will begin to associate the position in the air, and the right or left hand, with subject or predicate.
