Beginners: Dr. Root demonstrated the two rook checkmate and students practiced it. (Lesson plan is in Children and Chess: A Guide for Educators).

Showed the last three moves of a 10-move Ruy Lopez Exchange Variation opening. Then students played out an endgame that results from the Ruy Lopez, Exchange Variation pawn structure. We discussed how the pawn structure choices you make in the opening have effects that stretch into the endgame.
