I taught my 8 y.o. grandson this summer on a 7' 4wt cane rod and he did just fine. For his birthday I bought him a Cabela's traditional 7'-6" 4 wt and again he did well with it. I think anything between 7' and 8' in either a 4,5,or 6wt will be perfect and also would not rule out a 8'-6" rod but would suggest something shorter.

PAangler is correct in that they will catch many moore trees than fish
