E.G.W. advice to elementary teachers

Even a child is known by his doings,

whether his work be pure, and whether it be right.

Proverbs 20:11

"Teachers should sometimes enter into the sports and plays of the little children and teach them how to play. In this way they may be able to check unkind feelings and actions without seeming to criticize or find fault."
