Mr. Davies hummed a merry tune as he unlocked the classroom door. A small, rectangular box sat on his desk. He picked it up and found it surprisingly heavy. He shook it, and heard a faint rattling sound. He ripped off the wrapping paper, revealing a plain wooden box. Inside, nestled in shredded paper, were hundreds of small, colorful dice.

He picked up a handful, letting them cascade through his fingers. He imagined all the lessons he could spice up with them. History lessons, grammar lessons, everything could be turned into a game. The idea sent a ripple of excitement through him.

He spent the next hour rolling the dice, arranging them into patterns, and creating a ridiculously complex scoring system. He could not wait for Monday.
