These are some of the basic communication visuals taken from Boardmaker.

You may print, cut and laminate and get the student/ child to use it as picture exchange communication.

I would suggest starting with 3 basic visual cards, teaching and modeling to the child first in a daily context. Once the child, can identify/understand the visual or is able to perform picture exchange, you may then introduce 1 to 2 next visual cards for the child.
