Choose the number that is of the type named in the question e.g. fraction, prime, decimal, etc.
Home / 4th grade / Comparing numbers / Naming numbers / Select types of number
In this topic you are given the name of a type of number and you have to choose from the offered numbers which one is of that type.
For instance, the question might be "Negative" and you are offered the options "½", "-6", "3.5" and "890". You can see that the second answer is the only negative number in the list. The types of numbers you will be asked to distinguish are listed below.
Positive Numbers
Positive numbers are numbers greater than zero. They can be whole numbers or decimals. For example, 2, 5, and 12 are positive whole numbers, while 1.5 and 3.25 are positive decimals.
Negative Numbers
Negative numbers are numbers smaller than zero. They are written with a minus sign (-) in front of them. For example, -3, -6, and -15 are negative numbers. We can also have negative decimals, like -2.7 or -0.25.
Even Numbers
Even numbers are numbers that can be divided by 2 without leaving any remainder. In other words, they are numbers that can be split into two equal parts with nothing left over. Examples of even numbers are 2, 14, 52, 86 and 934. Notice that it is the units digit which is important in deciding if a number is even.
Odd Numbers
Odd numbers are numbers that cannot be divided by 2 without leaving a remainder. In other words, if you try to split an odd number into two equal parts, you will always have one part that is bigger than the other. Examples of odd numbers are 1, 23, 35, and 77. Again, it is the units digit that will allow you to tell if a number is odd or even.
Decimals
Decimal numbers are numbers that have a whole part and a fractional part separated by a decimal point. The fractional part represents a part of a whole. For example, 0.5 represents half, and 0.25 represents one-quarter. Decimals can be positive or negative, like 2.75 or -1.3.
Fractions
Fractions are numbers that represent a part of a whole. They are written as one number above another, separated by a horizontal or diagonal line. The number above the line is called the numerator, and the number below the line is called the denominator. For example, ½, ¾, and ⅘ are fractions.
Prime Numbers
Prime numbers are whole numbers greater than 1 that have only two factors: 1 and the number itself. In other words, prime numbers cannot be divided evenly by any other numbers except 1 and themselves. Examples of prime numbers are 2, 3, 5, 7, and 11.
This topic gives you the names of types of numbers and asks you to choose from the options the number that is of that type.
