This is the first page of the Set Two pentatonic scale-tone practice patterns - exercises Nos. 1 to 10. They are in six-eight, and all in the all-white-key pentatonic major scales C, F and G.
Work on each one until it feels natural under the hand and you have discovered a reliable fingering - one which doesn't have you running out of fingers.
