I actually got to practice my Navajo numbers today, as the incomplete, accidentally released-into-beta-today Duolingo Navajo course has a unit on numbers.
The incomplete Hawaiian course that also was accidentally released today too doesn't have a unit on numbers so far, so I wasn't able to do the same for Hawaiian.
