We worked on closed chords and moving the shapes up the neck (pg 51). Practice these shapes with the exercises on page 52. Also play Buffalo Gals. Play and sing in first position and then change keys by moving up the neck. These chords shapes also take patience and determination. Don't hurt yourself working on them. Here's the way to go at it:
Do a little at at time.
Lead with the finger that is hardest to place and then let the others fall in behind it.
Don't fret over the sound, maybe don't even strum
Just work on letting your fingers get used to the shapes.
Put the uke down .... walk away.
Later on, go back and do it again.
Before too long your fingers will start to go there on their own.
