Hey guys,
Here is a page that has all the note order variations for playing triads in a single key.
For example, in the key of G you can go up the scale and play the notes of each triad in root position, or 1-3-5: G-B-D, A-C-E, B-D-F#, etc.
OR you could play the same triads, but start on the third of each triad instead of the root, (so playing 3-5-1 or aka first inversion) so then would go: B-D-G, C-E-A, D-F#-B.
You are still playing the triads going up the scale, just starting on a different note. If you run through all the possibilities for all the combinations of notes in the triads you get a total of six different ways to play them:
1-3-5 - G,B,D
1-5-3 - G,D,B
3-5-1 - B-D-G
3-1-5 - B-G-D
5-1-3 - D-G-B
5-3-1 - D-B-G
This page has them all, in triplets, in the key of G major only, and only one octave.
Knock yourself out doing the remain keys or going for two (or more) octaves.
Also, mix-em up, play one triad 1-3-5, then the next one 5-3-1, then the next one 3-1-5, go nuts, combined them however you want.
Including a link to an MP3 of what they sound like also -

You can do this for 7th chords, 9ths etc, and it gets crazy quick, but plenty to practice here with just good ol' triads.
