Teaching a 7 year old chess end games

[CarpeDiem]

I've done some teaching on this and can recommend some things...

1)Start with 2 queens and the "rook roller" mate. ex: white Qa1, Qb2, Black king h3. Check down the board.
Don't worry about stalemate for now.

Try it with a queen and rook. Switch which is closer to the king

Then try 2 rooks

Then try queen & king v king.
K & R v king

The key idea here is that your child can learn to control the game versus making random moves.

Next simple king and pawn vs. king--very simple, like showing a pawn defeating a king racing down the board at first (emphasizes promotion) then the king as blocker. Only aftger these is opposition necessary.
