Dr. Alexey Root taught how pawns move and capture to the beginners at Greenhill School. She did not cover en passant. Then the beginners played the Pawn Game from Dr. Root’s book Science, Math, Checkmate: 32 Chess Activities for Inquiry and Problem Solving. For the intermediate and advanced groups, Dr. Root had the students play Battleship Chess, a drill from her first book Children and Chess: A Guide for Educators.
