Inspired by a post on Grognardia, my 1-page d20 D&D rules. Planning to use these with my son once he learns to talk.
Introductory Dungeons & Dragons
I recommend Basic Fantasy RPG as the template, but any OGL version of d20 D&D should work (eg 3e D&D, C&C), as long as it uses "higher is better".
Task Resolution Mechanic: Roll Target Number or higher on d20+Level to succeed.
Combat: PCs normally act first, unless surprised, then alternate. A hit inflicts 1 Wound.
PC Fighters
Level XP Wounds to Kill
1 0 2

7 640 8
8 1200 9
9 2400 10
10 3600 10
+1 +1200 +1/2 levels
Base AC: 17 (heavy armour), 15 (medium armour), 13 (light armour), 11 (no armour)
Shield: +1 AC.
2-handed weapon: +1 to-hit.
Fighting Defensively: Add Level to AC rather than to Attack roll.

Magical weapons and armour bonuses apply normally.
Healing potions restore 1 wound.
D&D monsters may be used normally. A monster's Level = its Hit Dice
Monster Attack Bonus & Wounds both = monster Level
Damage: Monsters normallly inflict 1 wound per attack. For BFRPG, S&W etc those that do 2d8 on a hit can inflict 2 wounds, 3d8 3 wounds, etc.
XP: Monster XP totals are divided by 10 (1 orc = 1 XP). Optionally 100 gold = 1 XP.
Sample monster stat block:
Orc: Level 1 AC 14 XPV 1
