What are integers for a nine year old?

Answer 1

integers are whole numbers, not fractions, and they can be more or less than zero. basically, they are whole numbers. Look at it like this. you have a barrel. add in one hot ball of fire, symbolising adding one. so one hot ball makes it one bigger. then add one cold ball of ice symbolising subtracting one, to make the number smaller. If you start by adding one cold ball, the number is colder than normal at the start, and is less than zero.

hope this helps!

Answer 2

It is about second grade when the concept of integers is generally introduced. One could look at it from the perspective of a child who, at lunch, borrows a sandwich from another second grader. The next week the child is asked to repay his debt, and although both children have an intuitive sense of what this means, neither can express the debt on paper. This is where the integers are introduced. Integers encompass all numbers that are included in the natural number set, but also encompass all of the negative whole numbers as well. Thus numbers such as 0, 1, 2, 3 are in the set of integers, but now -1, -2, -3 are also included in the set. In fact, for every positive number in the set of integers there is also a number equal in value, but opposite in sign. Integers, like natural numbers, do not include fraction such as 1/4. The formal definition of integers could be stated as:

I= {. . ., -4, -3,-2, -1, 0, 1, 2, 3, 4, . . . }

The collection of all such whole numbers, positive, negative or zero.

Answer 3

integers are real numbers that can be expressed as fractions an example is 5 or a half. Pi and square roots of non square numbers like 2 are not integers because they go on forever.
For a nine year old normal numbers and simple fractions

Answer 4

I presume you're looking for a way to explain integers.

Basically, integers are the counting numbers. They are whole numbers that can be positive or negative and including zero.

Answer 5

Whole numbers, not fractions or decimals. Includes zero and negative numbers. The word is related to integral (as in "we have an integral garage" - there's one whole building of which the garage is a part") and integrated ("the new housing estate has integrated well with the town" - formed a single, cohesive social unit).

Answer 6

Much the same as they are for everyone else: whole numbers...and it makes me sick that a nine year-old is being introduced to the concept in school (presumably) but isn't having it explained properly.

Answer 7

integers are whole numbers, like whole chocolate biscuits. when you bite one in half, it becomes a fraction of a biscuit. I'm not sure what they are if you just lick the chocolate off the top though.

Answer 8

integers is a fancy word for positive and negative numbers.

Answer 9

Intergers are whole numbers: 1,2,3 etc. Zero and minus number are also integers
