This activity includes 24 task cards along with an answer sheet. It can be used in order to review 8.NS.2 concepts:
Students locate rational and irrational numbers on a number line.
Students order and compare rational and irrational numbers.
Students also understand the value of square root can be approximated between integers and that non-perfect square roots are irrational.
You may use this activity in a variety of ways. I used it as a review activity and placed students in groups of 3-4 students. I encouraged the students to work together to discuss and solve the problems on the task cards.
An answer key is included.
