'Minimum' D&D

There's a discussion in the B/X Facebook group about introducing young kids, in this case aged 5-7, to D&D.

I've been finessing the idea of a stripped-down character sheet - I started here:

... where anything in blue is just book-keeping by the DM and not necessary for the PC to know. Why should a player be bothered about a save against Death Ray if they never encounter a Death Ray? What does it matter?

Eventually, especially due to discussions with someone else on the thread, I started adding pictures, and arrived at this (where the 7hp in 'Health', and the 43 on the bag of gold, are pencilled in):

So I guess the question is, is this really D&D? Is the minimum information presented on this 'character sheet' enough to play something that's recognisable as D&D?
