Classifying rational and irrational numbers

Why do we classify numbers? Why do we give them names, like integers, irrational numbers, or negative numbers? For the same reason we classify anything, we want to make sure that everyone has an understanding of what specific numbers are called and what they mean. Numbers are our way of keeping order. We count the amount of money we have. We measure distance. We use percentages to indicate a sale. A real number is any value of a continuous quantity that can represent distance on a number line.

In simple words, it is the ratio of two integers.

The earliest use of numbers occurred centuries ago in the Middle East to count, or enumerate items. Farmers, cattle herders, and traders used tokens, stones, or markers to signify a single quantity—a sheaf of grain, a head of livestock, or a fixed length of cloth, for example.

There are several other number classifications as well. Did not receive OTP? Q3 Give examples of rational and irrational numbers. If your looking for a way to identify rationals and irrationals: a rational number is a number that can be expressed as an integer by an integer. After a whole-class introduction, students work collaboratively in pairs or threes classifying numbers as rational and irrational, justifying and explaining their decisions to each other. Now, you have pi, 3. For example: 1, 9, and So it's clearly rational. Would it be accurate to say that whole numbers are positive numbers and zero? Rational numbers can also be positive or negative.
