Regents Exam Prep Center: Irrational Approximations

Providing one instructional activity, one practice exercise, and two teacher resources, the information at this website is geared toward young scholars who already understand rational and irrational numbers. The instructional activity has explanations of what happens when a irrational number is "rounded" and provides examples of rounded irrational numbers. The practice activity is a quiz testing your understanding of approximations (using a calculator). The teacher resources provide tips for simplifying and enriching the instructional activity.
