The amazing accomplishments of the ancient Maya as well as the Maya currently living in Mexico's Yucatá n Peninsula are highlighted in this collection of 25 creative, educational, hands-on projects. Covering everything from the 20-base numbering system to the Maya's  extensive trade relationships,   kids learn about appeasing the gods with a "jade" ceremonial mask, language  development with a screen-fold book for drawings and hieroglyphs, and Maya astronomy with a sand art picture of the cosmos. Informative text and sidebars teach  about the Maya's impressive achievements in science, math, language, music, medicine, and architecture; and their daily activities and management of natural resources.
