Song: "Knock knock Hello"

♫ Hello! (Hello!) [Wave with your right hand.]
Hello! (Hello!) [Wave with your left hand.]
Come in. [Motion to come inside.]
Let's sing. [Pretend you are singing into a microphone.]
Let's play. [Run in place.]
Hello! (Hello!) [Wave with your right hand.]
Hello! (Hello!) [Wave with your left hand.]
Knock, knock, knock. [Pretend to knock on a door.]
Come on in! [Motion for someone to come inside.]
Let's sing. [Pretend you are singing into a microphone.]
And play. [Run in place.]
And learn together. [Tap your finger on your temple.]
Knock, knock! [Thrust your fist in the air.] ♫
