This lesson challenges students to use Pythagoras' Theorem to solve a problem from an ancient Chinese text. They make physical models of the problem and use this to construct a graph. They use algebra skills associated with binomial expansions and simplification of fractions to show that the general solution given in the Chinese text gives identical results to that developed using modern mathematical techniques. The lesson is outlined in detail including curriculum links, discussion points and student handouts. This sequence is part of the reSolve: Maths by Inquiry program.
