How many times has a question said round to the nearest integer or leave your answer as a rational number, and your students have no idea what this means? Most of our classes cover Sets of Real Numbers at the beginning of the course and then students are expected to use this knowledge over and over again, but many forget what the sets of real numbers are.
This coloring activity is a quick and fun way for your students to test their knowledge of sets of numbers. They can work independently or with a partner. You can assign it as a homework assignment, Friday afternoon quick review activity, or leave with a substitute to keep them engaged in learning.
