I had the opportunity to work on this. I let my son try the demo last week. Hours afterward at dinner I asked him to explain binary to my wife.
"Mom, imagine you have the number 101 in binary. The first 1 is the fours spot, so you have 4. There's none in the twos spot. and 1 in the ones spot. So that means you have 5."
Two days later he came into my office and asked if he could do more tutor.

That's a huge win in my book!
