TLF ID L1936
Work out how many acrobats are needed to form triangle-shaped human towers. Start by building a triangle with three acrobats: two acrobats in the base layer and one acrobat standing on their shoulders. Examine a table and graph of the total number of acrobats in the towers. Predict the number of acrobats needed to build bigger towers. Describe how the number pattern is formed. This learning object is the second in a series of five objects that progressively increase in difficulty.
