Well, here's the lesson plan:
Have him make a pyramid, 3 sides, 4 sides, then 5 sides, possibly 6 sides.
Then, a cube. Then, a 12-sided dice.
Then, once he's gotten shape down, teach him Earth Release: Rock Spear, which is essentially just shaping earth, it should come easy. If you want to, teach him how to make a small wall maybe. Focus on the proportions of the wall, its density, and its base strength (see if it's too top heavy)
GO VERY SLOWLY, TAKE EVERY OPPORTUNITY TO SAY HE DID SOMETHING WRONG 
Nothing against you, blind, I just put all my students through very slow, deliberate training. Through this, they feel and understand the element, and are much stronger w. it
