The Warlord's Messengers

The warlord�s presence is requested at the emperor�s banquet in two weeks, but he is sixteen days away by horseback. Using their math skills, ingenuity, and the wind, Chuan and Jing Jing reach the warlord�s camp and encourage him to use their sailing cart to travel to the feast. The Warlord�s Messengers is the sixth book in the acclaimed Warlord�s Series, and includes directions for making your own windsock as well as suggestions for velocity-related math activities.
