Home Numbers & Operations Prime and Composite Numbers Prime and Composite Numbers Worksheets Here are more than 25 prime and composite number worksheets, carefully designed for grade 4 through grade 6 students. We will clearly discuss the concepts of prime, composite, co-prime, and twin prime numbers. We can classify all natural numbers as prime and composite. Prime Numbers: Any natural number that has only two factors, the number itself and 1 is known as a prime number. Eg. 1, 2, 3, 5,……11,……23,…..97,… The number 3 has only two factors. That is, it is only divisible by 3 and 1. (Without leaving a remainder). Thus 3 is a prime number. The number 2 is the smallest prime number. Interestingly, its the only even prime number which means all other prime numbers are odd. Composite Numbers: Any natural number that can be divided by other natural numbers and with the number itself and 1 is a composite number. Eg. 6, 8, 9,…..86,…99,… With 1 and 6, the number 6 has other factors like 2 and 3. Thus the factors of 6 are 1, 2, 3, and 6 which makes 6 a composite number. 1 is the only number which is neither prime nor composite. Twin primes: Prime number pairs which differ from each other by 2 are twin primes. Eg. 3 and 5, 11 and 13, 41 and 43….. In the above shown pair of numbers, the difference between the numbers is 2. Co-primes: Numbers that do not have any common factor other than 1 are called co-prime numbers. Eg. Number pairs 2 and 3, 3 and 4, 4 and 5…………17 and 23, 29 and 31,…….. 29 and 31 are both twin primes and co-primes. All twin primes are prime numbers, whereas all co-primes need not be prime numbers.

Home Numbers and Operations Squares and Cubes of Numbers Squares and Cubes of Numbers worksheets Understanding squares and cubes of numbers is a crucial part of building strong math skills. From calculating area and volume to solving algebraic equations, this concept appears across many topics in mathematics and real-life applications. Squares and cubes always follow a pattern. Look at the figures shown below. Look at the pattern of dots arranged in the figures shown above. They are arranged in square shape and can be called perfect squares. Thus the number obtained by multiplying a number by itself is a square number. The first 5 square numbers are given below: 1 x 1= 1 2 x 2= 4 3 x 3 =9 4 x 4= 16 5 x 5= 25 To begin, squaring a number means multiplying it by itself. For example, the square of 4 is 16 because 4 × 4 = 16. On the other hand, cubing a number means multiplying it by itself twice. So, the cube of 3 is 27, since 3 × 3 × 3 = 27. These simple operations form the basis of many advanced mathematical ideas. As you move forward, it’s helpful to remember the squares and cubes of smaller numbers, especially from 1 to 20. Memorizing these will speed up your calculations and give you a strong foundation for topics like exponents, polynomials, and geometry. Cube Numbers: The first 5 cube numbers are as follows: 1 x 1 x 1= 1 2 x 2 x 2= 8 3 x 3 x 3= 27 4 x 4 x 4= 64 5 x 5 x 5= 125 Print these worksheets to know more about perfect squares and perfect cubes.

Home Numbers & Operations Counting & Cardinality Counting and Cardinality free worksheets for pre-school kids Counting & Cardinality is the foundation of early math learning. It teaches children not only how to count in sequence but also helps them understand that numbers represent quantities. This essential skill prepares young learners for more advanced math concepts later on. To start, children begin by learning to count from 1 to 10. They recite numbers in order and match them with objects—like counting blocks, toys, or steps. This simple activity helps them connect spoken numbers to actual amounts, which is the first step in developing number sense. As they progress, they begin to understand that the last number said when counting represents the total number of items in a group. This is known as cardinality. For example, when a child counts five apples and says “five,” they recognize that the group has exactly five apples—no more, no less. Next, kids practice comparing quantities using terms like more than, less than, or equal to. They also learn to recognize written numerals and match them to a quantity. These activities support both counting fluency and number recognition. In addition, hands-on activities like counting games, puzzles, and interactive songs make learning fun and engaging. These tools help children develop a deep, lasting understanding of numbers through repetition and real-life examples. By practicing daily, children build confidence and accuracy in counting.
