If this is a trick question, then use 11.
(as two of the numbers, a 1 and a 1 from the list of numbers)
11+1+1+9+9, this uses '6' of those numbers he/she gave and adds to 31.
Otherwise to prove it can't work, show that all 9 numbers given add up to 43, 12 more than needed, so do any of 3 of the numbers add up to 12? No, closest is 9+1+1=11, or 8+5+1=13. This teacher is either really trying to be tricky or made a mistake. Good Luck!

It's not possible using the single digits.
The best I could get was 1 + 1 + 5 + 8 + 8 + 8 but you aren't allowed to use more than two 8s.
If you are allowed to combine digits into a single number you could do:
9 + 9 + 11 + 1 + 1

Either you are pulling our legs or your kid's teacher is one sadistic SOB.
