Activity Overview
Students learn to identify real numbers as rational numbers and irrational numbers. They review rational numbers as repeating decimals, and irrational numbers as non-repeating decimals. They also review commutative, associative, distributive, as well as inverse properties of real numbers systems. Students learn the Pythagorean theorem, and the formula for finding the circumference of a circle.
Before the Activity
Install Topics in Algebra 1 (Chapters 1-4) App on the calculator using one of these two methods:
TI Connect™, a TI Connectivity Cable, and the Unit-to-Unit Link Cable
TI-Navigator™ "send to class" feature
See the attached PDF file for detailed instructions for this activity
Print pages 1-23 to 1-29 from the attached PDF file for your class
During the Activity
Distribute the pages to the class.
Follow the Activity procedures:
Write three different irrational numbers
Use the real number properties to solve multiplication problems
Determine if a given number is a rational or an irrational number
Decide which single property (commutative, associative and distributive) is represented in an equation
Use the Pythagorean theorem to draw a triangle whose two legs are 1 unit each, and hypotenuse is √2 units
After the Activity
Students will complete the Student Worksheet and analyze the results.
Review student results:
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
