Factoring Worksheets for Grade 4

This factoring worksheet is designed for fourth-grade students. The purpose of this worksheet is to introduce the concept of factors that will help kids expand their knowledge in mathematics. So kids, let’s understand about factors. Factoring is a type of process where we break down numbers into smaller parts, and parts should give the same number when we multiply all of them together. We hope this worksheet will grab kids’s attention and increase their interest in solving math.

Factoring Numbers Between 4 to 50 Worksheet For Grade 4

1. 5 ->1,5
2. 12 ->1, 2, 3, 4, 6, 12
3 . 16 -> 1, 2, 4, 8, 16
4. 25 ->1, 5, 25
5. 30 ->1, 2, 3, 5, 6, 10, 15, 30
6 . 36-> 1, 2, 3, 4, 6, 9, 12, 18, 36
7 . 42->1, 2, 3, 6, 7, 14, 21, 42
8. 50-> 1, 2, 5, 10, 25, 50

In this exercise, we have to find factors of a number between four to fifty. Above, there are a total of eight quarries and for each, we need to follow a basic rule. First, we have to break a number into smaller parts and remember that when we are calculating all parts, we should get the same number. Like 5 -> 1,5. When we calculate both (1×5), we are getting the same number. Let’s take an example: 12 – As per the rule, the factor will be 1, 2, 3, 4, 6, 12. You can check if the factor is correct or not by multiplying all the parts: 1 x 12 = 12, 2 x 6 = 12, 3 x 4 = 12, 4 x 3 = 12, 6 x 2 = 12, 12 x 1 = 12. 

Factoring Numbers Between 50 to 100 Worksheet For Grade 4

1. 52 -> 1, 2, 4, 13, 26, 52
2. 58 ->1, 2, 29, 58
3. 64 -> 1, 2, 4, 8, 16, 32, 64
4. 69 -> 1, 3, 23, 69
5. 74 -> 1, 2, 37, 74
6. 80 -> 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
7. 95 -> 1, 5, 19, 95
8. 100 -> 1, 2, 4, 5, 10, 20, 25, 50, 100

In this exercise the numbers are higher, we have to find out the factors of a number between fifty to hundred. Children don’t have to worry about it; we have done the above exercise and this exercise will also be performed in the same manner. We believe that the kids have solved all the above queries and now they are ready to handle this exercise. If kids solve this exercise, it means that they have understood the first step of our factoring worksheet. 

Prime Factor Tree Worksheets For Grade 4

In this exercise, kids will learn how factorial numbers are represented by a graph. A prime factor tree is a simple graph that is used to represent the factorial of a number. Above, we have a total of six queries, and in each, we have two empty circles and we need to fill the circle by breaking the number into smaller parts. Remember the parts should be equal when we are multiplying. For example: 14. We can divide 14 into two smaller parts, which are 2 and 7. When we calculate 7×2 = 14, we are getting the same number, which means we have got the correct smaller part. We would be very happy if kids performed this exercise on their own. It is a simple exercise and it helps them to understand the pictorial representation of a number. 

Prime Numbers 2 to 50 Worksheets For Grade 4

    1. 2

• • prime factor:- 2
  • is prime? – Yes

2. 8

• • prime factor:- 2 x 2 x 2
  • is prime? – No

3. 11

• • prime factor:- 11
  • is prime? – Yes

4. 16

• • prime factor:-2 x 2 x 2 x 2
  • is prime? – No

5. 24

  • is prime? – No

6. 29

• • prime factor:-29
  • is prime? – Yes

7. 31

• • prime factor:- 31
  • is prime? – Yes

8. 42

• • prime factor:- 2 x 3 x 7
  • is prime? – No

9. 47

• • prime factor:- 47
  • is prime? – Yes

This exercise introduces a new concept where kids will learn about prime numbers. A prime number is nothing but a number bigger than one and they don’t have any divisors except one or themselves. Above, we have a total of nine queries and for each, we need to identify whether the number is prime or not. To solve this, we only have to check whether the number is divisible with two or not, if yes then the number is not prime, if no then the number is prime. It is a simple exercise, and we hope kids will solve this without any help.

Prime Numbers 50 to 100 Worksheets For Grade 4

  1. 53

• • prime factor:- 53
  • is prime? – Yes

2. 58

• • prime factor:- 2 x 29
  • is prime? – No

3. 65

• • prime factor:- 5 x 13
  • is prime? – No

4. 67

• • prime factor:-67
  • is prime? – Yes

5. 74

6. 76

• • prime factor:–2 x 2 x 19
  • is prime? – No

7. 83

• • prime factor:- 83
  • is prime? – Yes

8. 90

• • prime factor:- 2 x 3 x 3 x 5
  • is prime? – No

9. 97

• • prime factor:- 97
  • is prime? – Yes

Now the numbers are higher than the previous, but we believe nothing is impossible if we decide to do something. Above, we have a higher number range starting from fifty to a hundred. This exercise should be performed quickly, the process will be the same. We only have to check whether the number is divisible by two or not. If the number is divisible, that means the number is not a prime, and if not that means the number is prime. 

Divisibility Rules Math Worksheet For Grade 4

• 2 -> A number is divisible by 2 if the last digit is 0, 2, 4, 6, or 8. Example: 248 is divisible by 2 because the last digit is 8.
• 3 ->A number is divisible by 3 if the sum of its digits is divisible by 3. Example: 381 is divisible by 3 because 3+8+1=12, and 12 is divisible by 3.
• 5 ->A number is divisible by 5 if the last digit is 0 or 5. Example: 35 is divisible by 5 because the last digit is 5.
• 9 ->A number is divisible by 9 if the sum of its digits is divisible by 9. Example: 378 is divisible by 9 because 3+7+8=18, and 18 is divisible by 9.
• 10  ->A number is divisible by 10 if the last digit is 0. Example: e.g. 60, 110, 850

In this exercise, kids need to check whether the number is divisible or not. If yes, then make a correct sign; if no, then mark the wrong sign. To solve this exercise, we need to follow the above rules. First, you have to write down the rules in the above empty box and as per the rule, we have to solve this exercise. It is a simple exercise that helps kids improve their number sense. We will be happy to know if kids solve, this without any help.

In this exercise, we have to write down the first five multiples for each number. It is a simple exercise that improves kids’ mathematical skills and encourages their confidence to handle more complex problems. Above, we have a total of seven exercises, and for each, we have five empty boxes that need to be filled. We hope at this stage kids have understood our concept and they handle this exercise.
