Improv-a
A fun way to get to know a few scales, practice with a backing track and then branch out into improvisation once you're used to playing the scale notes.
Take it as sloooowly as you like, backwards, forwards, in any order - it will sound just as good.
There's a tricky E7 in the C major chord progression so if you hear a slight dissonance at any stage, that'll be why. Just keeps things interesting!
