OBJECTIVES: At the end of the lesson, students are expected to: describe and illustrate the real numbers; plot the set of real numbers on a number line; and relate and appreciate the importance of real numbers in real life through writing a journal.
REAL NUMBERS
REAL NUMBERS -are all numbers that are not imaginary. SUBSETS OF REAL NUMBERS -Counting or Natural Numbers -Whole Numbers - Integers -Rational Numbers -Irrational Numbers
Counting or Natural Numbers consists of all positive integers that we use to count starting with "1" and so on.
Whole Numbers exactly like the subset of counting numbers that includes zero "0."
Integers includes whole number (not a fractional number) that can be positive, negative, or zero.
