First the movement/behaviors. Read the book all the way through one time so that your students can savor the writing and illustrations. Then read it again and focus on the words describing the action. Let your students move/behave the way the word tells them: quick, slow, small (Can you be very, very small?), large (Can you be very, very large?), sad, happy, nice, mean, cold, hot, weak, strong, loud, quiet, tough (How can you show that you are tough?), gentle (How can you show that you are gentle?), brave, shy, tame, wild, lazy and busy.
Were the students unsure about the way to act with some of the words? Say, for example, they are not sure about how to act "tame". Write the words "wild" on one side of the board and "tame" on the other. Ask the children to brainstorm some things that might be wild and some that might be tame. Wild things may be easier to start on first. When they have a list of a few tame things, talk about how those things behave in a calm way. They don't scare people. You may mention that someone or something who is "gentle" may act in a similar way. Some animals can be tame. Some animals, may seem tame at times, but are always meant to be wild.
