100 Mighty Dragons All Named Broccoli by David LaRochelle and Lian Cho is a clever, fun book that encourages simple math practice. High atop a windy mountain, there are 100 dragons of all different shapes, sizes, and colors, but they’re all named Broccoli! As the book progresses, the dragons all meet with different adventures: taking a rocket to the moon, starting a heavy metal band in New York, playing for the Green Bay Packers, and moving to West Virginia. Each time, the reader is prompted to add or subtract how many dragons are left until, finally, there’s just one dragon remaining…although not for long!
