The major pentatonic is often more useful as a phrase source than as a theory topic.
In C, the notes are:
C, D, E, G, A
A first motif
Same notes, shorter phrases
Take the same notes and make them breathe:

One practical exercise
- Play only C, D, E, G, A.
- Make a two-bar phrase on Cmaj7.
- Answer it on Fmaj7.
- Resolve it on G7.
- Repeat with a different rhythm before changing the notes.
A more melodic version
Instead of running upward, keep one small shape and move it:
One thing to listen for
On this progression, E and A sound especially sweet on the major chords, while D and G help the line turn toward G7.
That is enough material for a full practice session without adding more notes.
