Jerome Fine replies:

With my grandchildren, I discovered a way to make binary
numbers interesting. We started with the concept that each
finger represented a ZERO or a power of two.

All fingers down was ZERO.

Baby Finger UP was ONE.

Ruby Ring UP was TWO

Both Baby Finger and Ruby Ring was THREE.

Tobby Tall UP (by itself) was FOUR

Tobby Tall and Baby Finger was FIVE

Tobby Tall and Ruby Ring was SIX

Tobby Tall and Ruby Ring and Baby Finger was SEVEN

Peter Pointer (by itself) was EIGHT

Peter Pointer and Baby Finger was ...

We rarely got beyond this point since everyone was
laughing so much by then, by it made the game a lot of

If they were able to grasp the meaning of powers of two
and get to EIGHT, then they already knew what having
Peter Pointer and Baby Finger were supposed to mean!
