Description:

Learners create an Incan counting device called a quipu (pronounced kee-poo). Similar to an abacus, a quipu is a series of strings tied together, with a complex set of knots tied in each string to represent different numbers. Learners create their own system of representation, choosing different colors of string to represent different things important in their lives. For example, they could use knots in the string to indicate how old the different people in their family are, or how many years they lived in each of the places they have been in their life. A decimal system can be used to represent numbers larger than 10.
