The "toe touch" is a simple dance move that requires a little bit of flexibility and rhythm. It involves situating the feet at a shoulder's length apart. Move your right foot in front of the body and slap the foot with your hand. Then, move the same foot back into position and repeat, except move the foot behind your back when you slap it with your hand. Repeat with the left foot.
The "cool walk" is a move in which a child picks up one foot and raises it to the waist. Then set the foot down on the outside of your other foot. Pick up your other foot and repeat, placing the foot on the outside of your other foot. The "crisscross" also uses the feet and is a slight variation of the "cool walk", but it uses more upper body and bouncing.
The most simple hip hop dance moves for children involve rhythmic stepping that may awaken their hip hop sensibilities. You can play some hip hop songs and children can move their legs back and forth to the beat of the music. In addition, they can roll and flail their arms to the beat. For example, The Happy Kids Festival teaches hip hop dance classes in which children face a mirror and practice feeling the rhythm of the music.
A simple arm move for children is the "push, push, elbow, elbow." This move involves children moving their arms twice in a wave-like motion to the beat and then they throw each elbow, one at a time, to the side. This results in two wave-like arm motions (the "push, push") and two elbow thrusts (the "elbow, elbow"). These arm motions combine to form this simple move, which befits young hip hop dancers.
