I made this worksheet for a younger student who has not yet been introduced to dotted half notes. You can find worksheets like this quite easily, but it was hard for me to find one that covered only these three note values, so, I made my own!

I recently used these stars for my younger students when they learned Twinkle Twinkle Little Star from My First Piano Adventures (Faber and Faber). I printed 1 copy of this and cut out a row of start each week until the student had learned the song well enough to play with out them.
