TLF ID L1939
Work out how many acrobats are needed to form pyramid-shaped human towers. Start by building a square pyramid with five acrobats: four 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 last in a series of five objects that progressively increase in difficulty.
