Get your preschoolers acquainted with the concept of movement by talking about common words used to describe the different kinds of movement. First, introduce the students to basic forms of movement by asking them how they got to school. They may answer they walked or ran. You could then take the students out to the playground on a fair weather day to ask them how they use movement to play on various pieces of equipment; words you should be hearing include swinging, sliding, climbing and crawling. Starting a dialog about movement can help you build a vocabulary to define and describe different methods of movement in later activities.
Music goes hand in hand with movement as it provides rhythmic patterns that naturally make people want to move. Provide the students with some instruments to create their own rhythm and beat, or play a song for them. Ask the students to perform specific movements that cohere to the sounds they are listening to, or simply ask them to do their own creative dance interpretations of the music. Talk about the different ways the students moved around to help further advance your movement dialogue.
After you've covered the ways in which people commonly move, branch out into how other species move with an interactive learning activity. Call out the name of a specific animal to the students, and then ask them to mimic the way the animal moves. For instance, a bird would flap its wings, a kangaroo would hop up and down, a monkey would swing its arms, and a snake would slither.
Statues provide an opportunity to examine one specific kind of movement, so show your class some examples of statues that demonstrate a frozen movement. You could use play clay to have the students create their own versions of the statues you examine for an artistic activity. For a more active game, have the students play freeze tag; ask them to move or dance around the room, and then when you tell them to freeze, they have to stay perfectly still like statues in that position. Have everyone look around to examine how everyone's bodies are positioned mid-movement.
