Education Labs group released the Math Worksheet Generator – a free application created specifically for Mathematics teachers, tutors, and others to help them create practice math problems along with accompanying answer sheets. The Math Worksheet Generator is based on the Microsoft Math engine and is able to deconstruct the logic of a sample math problem you provide (using the Math Input Panel if on Windows 7) and create many more examples to help test a students understanding of a particular concept.
