Children's anger presents challenges to teachers committed to constructive, ethical, and effective child guidance. This Digest explores what is known about the components of children's anger, factors contributing to understanding and managing anger, and the ways teachers can guide children's expressions of anger. Anger is believed to have three components: (1) the emotional state; (2) the expression; and (3) an understanding of anger (interpreting and evaluating). The development of basic cognitive processes undergirds children's gradual development of the understanding of anger. These processes include memory, language, and self-referential and self-regulatory behaviors. Teachers can help children deal with anger by guiding their understanding and management of this emotion using the following practices: (1) create a safe emotional climate; (2) model responsible anger management; (3) help children develop self-regulatory skills; (4) encourage children to label feelings of anger; (5) encourage children to talk about anger-arousing interactions; (6) use books and stories about anger to help children understand and manage anger; and (7) communicate with parents to involve them in helping children learn to express emotion. Children guided toward responsible anger management are more likely than those who are not to understand and manage angry feelings directly and nonaggressively and to avoid the stress often accompanying poor anger management.
