This graphic organizer introduces students to classifying rational and irrational numbers.
First, with the help of the teacher or textbook, students fill in a number vocabulary page, which includes terms like integer and terminating decimal. These terms are important to the understanding of rational and irrational numbers.
Next, the following sheet gives students a list of numbers. Students attempt to turn these numbers into fractions without changing the value.
Then, students can look over the list to determine which numbers are rational and which are not. If a number can be converted into a fraction, it is rational.
The download has 2 pages of handouts as PDFs, along with answer keys.
Common Core Standard:
Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.
Extension: Check out my Rational and Irrational Numbers Puzzle to see if your students can identify rational and irrational numbers.
