For April 7, the Greenhill School chess beginners notated the four moves of the Scholar's Mate and learned how to defend against it. The Scholar’s Mate lesson plan is in Dr. Alexey Root’s book Read, Write, Checkmate: Enrich Literacy with Chess Activities.

The intermediate and advanced played the queenside castling (that is, 0-0-0, castling on the "queenside" of the board files a-d) version of the Game Theory challenge from Dr. Root’s book Thinking with Chess: Teaching Children Ages 5-14. They notated their games. Dr. Root had pairs show her their notated Game Theory (castling) games and tested students on the K and Q vs. K checkmate (intermediate) and K and R vs. K checkmate (advanced).
