- Welcome to the Primary Class. Here we teach children who are erePre-K through Second Grade. I am the Sunday School teacher, Mrs. Ruth Costable. We love to learn about Jesus in our class. We begin each class with prayer by one or more of the children. Next, we sing a few favorite songs that the children choose, and then on to our lesson. We have a Sunday School curriculum that has various Bible stories for each Sunday. These range from God’s creation to the accounts of great heroes of the faith; the birth, life, death and resurrection of Christ; and, the lives and work of the disciples. After the lesson each child completes a work sheet to take home. I also like to have a craft for each lesson. At the end of the class the children enjoy a snack.
