Texas Instruments: Knowing About Numbers

Students are always fascinated by imaginary numbers. In this video, Sal defines the imaginary unit, i, and shows that it has a cyclic nature when raising i to an exponent.

Students use a graphing calculator to find experimental probabilities by generating random numbers, using the random integer function. This Technology Lab accompanies Lesson 10-5 from the 2007 Holt, Rinehart and Winston Algebra 1 textbook.

Students explore the use of a calculator to investigate the relationship between divisors and remainders in whole-number division.

Students' will use the calculator to investigate the patterns formed by remainders in whole-number division.

This is a pre-test for a statistics class. Since most systems want data driven analysis, this is a great way to get data at the beginning of the course on how much students know about statistics.

Don't worry, this resource actually exists. Scholars learn about imaginary numbers and work on problems simplifying square roots of negative numbers. As an extension, they research the history of imaginary numbers.

This StudyCards stack enables students to review basic addition of positive and negative integer numbers. They are tested on their ability to add positive numbers, negative numbers and numbers in parenthesis.

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,...

When you start this activity, students receive a Venn diagram of real number sets (natural, whole, integer, rational, irrational)on their calculator. This same diagram is projected on the Activity Center screen at the front of the room....
