Dictionary - Interactivate


The Interactivate site by the Shodor Foundation includes an online dictionary. The definitions of many of the mathematical words and phrases include a link to a discussion page. The discussions are between a student and mentor where the words are used in the context of the mathematics.

For example, the words "denominator" and "numerator" are both mentioned in the "Fraction Adding and Subtracting" Discussion.
