Children who have difficulty speaking or being understood sometimes use pictures to communicate. In Primary a child could use pictures to tell a story, give a prayer, or present a talk.
The pictures* in the first box (1) represent the different parts of a prayer. In the second box (2) are things to be thankful for or to ask help with. A child who has a speech impairment would point to the pictures to give his prayer. Point to the pictures that would be appropriate for a prayer that you might give.
