Narrative:

Did it again! Utilizing a part-time pilot seems to cause more problems and bring about more errors than flying single pilot. We were at 11000 ft, cleared to 8000 ft. Somewhere in the descent, part-timer asked questions about our GPS. Distraction! At 7500 ft we noticed the altimeter. Missed both callouts for altitude.
