Sailing Away

Sail Away Sonatina by Judith R. Strickland is a wonderful collection of 3 pieces: Fish in Schools, Glassy Waters, and The Skipper.  The first and last were NFMC choices.  You can look inside here.

Fish in Schools utilizes the pedal and 8va with limited notes, so it is more early elementary.

Quick look:
4/4
pp, p, mp, mf, 
Notes: quarter, half, dotted half, whole notes and rests
middle C position, slur, pedal, 8va, hand movement, ritardando, a tempo, diminuendo, 

Glassy Waters is a smooth and calm piece.  It is of similar difficulty to Fish in Schools.  In addition to the above, you will find:

3/4 Time Signature
Key Signature: F
tie

Sail Away Sonatina is a little more advanced, more elementary than early elementary.  This is a lively little sailing piece with a lilt.

In addition to the above, you'll find:
eighth notes
staccato


Here's a video of the first of the three pieces.  (Not my recording or student.)
