The kick ball change is a step found in almost all forms of dancing, from ballet to tap to hip-hop. A kick ball change consists of three kicksteps and a ball change. That is, you kick your foot once and step forward, putting your foot down. Kick with the other foot and step your foot down. Switch to the other foot and kick, then step your foot down. Your other foot should be behind you a bit - you tap the ball of that foot on the ground, then tap the ball of your other foot (so you're "changing" balls). Hip hop is a loose, urban dance, so don't kick and step like a robot. Let it be bouncy and keep your arms loose.
