Remember that imagery can also limit students if used incorrectly. For example, asking students to hop like rabbits will more than likely result in a classroom of students hopping like rabbits and not exploring the many ways of hopping. Use visual aids to get ideas across to students whenever possible. Use percussion instruments and music to help stimulate the children to move. For example, a crashing drum could encourage students to leap high off of the ground.
Stillness is important.
Children get satisfaction from learning a phrase of movement and repeating it. Make the lesson challenging. Be generous with praise for the students' quality efforts.
