Here is a worksheet to introduce the spaces on the Treble Clef. I use FACE in the SPACE. We talk about how the Treble Clef is the girl clef and that girls like to make-up their face. I try any little story to get the concept to stick with the student. Of course FACE and space rhyme, making it easy, but when that bass clef is introduced the confusion begins. This worksheet has the student write a smiley face on the spaces.
