When ever I taught someone I would give them all the chords,
A B C D E F G
Tell them to make each chord as best as they could before each practice sessions, then end each session with making all again.
Then I would give them a simple 3 chords song they already knew to practice for the week. More chords of course as they got better.
After 6 months of that they could make all the chords and play some songs they liked.
Depending on how fast they learned, I would change up the order of the chords.
This week play D C A F B G E, play them a few times before you start and as you end each session. Next week I would change the order again and increase the amount of repitions.
Doing it that way exposed them to the next chords they would be using before they got there and they would not burn an order into their brain. So when they got to the next song part of the learning curve was already practiced.
Of course bar chords were also introduced along the way. So I would also suggest to start making the bar chord A at the 5th fret, also D at the 5th fret. At the beginning and end of each session.
You asked for idea's and thats what I did and why.
