Excellent idea Alan!
An added advantage of that kind of approach is that you can write on the
blocks - like the name of the component, its schematic symbol, and he
can see how to follow the schematic to connect them. Polarized devices
like diodes can be marked with the anode and cathode ends and
transistors can be marked with base, collector and emitter and the
difference between an NPN and a PNP can be clearly indicated.
Should make learning much easier for him and he will likely retain it
better.
Steps after that would be teaching the resistor color code and learning
how to read the values on capacitors - capacitor values are not trivial
these days.
Then an introduction to data sheets. By the time he is a couple years
older he will know more about circuits than many modern hams.

Here is one more approach:
I took a pine 1X2 and cut it into 3” pieces ; then screwed a couple of
Fahnstock clips into the
tops of each one near the ends. I then selected an assortment of 2 node
components plus a
pile of 6” cut copper wire pieces.
Whoopee…we could then make stuff…doorbell plus switch, simple diode rcvr, then
one with a
single transistor audio amp plus speaker (needs 3 NODE block), morse code key
and buzzer
etc etc
Tiny stuff can be intimidating…so the blocks fit his way of playing and we were
off and running.
A regen rcvr on a board for 40M can be a jump step and its all fun.
