Earthstones
During the Core Concept phase, teams earn earthstones by solving each challenge. Earthstones are provided by the WT Teaching Assistant and are small stones displaying one or two words. Each set of earthstones makes up a different key concept sentence, differentiated by different colors of stones and/or paint. After the teams have solved all of the challenges, the twist is that they only have half of the Earthstones they need to make complete sentences. Teams will have to pair up and share their resources, illustrating that individual success is dependent on the success of the whole group. By solving all of the challenges and completing their Earthstone sentences, your class can earn up to $500 in their first of three $500 awards.
