This interactive excel file has separate sheets which deal with inverse proportion where the functions are linear, quadratic and square root. Each sheet begins with a statement of the proportional relationship and values so that the constant can be calculated and the equation found. The student then substitutes given values in order to answer further questions. Tables of values and graphs illustrate each of the inversely proportional relationships. Answers can be revealed and new questions generated.
The final interactive sheet shows sets of mixed questions on inverse proportion with answers available.
There are a further four sheets of questions which may be suitable for use in the classroom.
