8 Math Division Tricks for Kids
1. The Halving Trick for Even Numbers
One of the easiest ways to divide is using the halving trick for even numbers. This is especially handy when you’re dividing a number by 2. The concept is simple: if a number is even, you can split it into two equal parts.
Example: If you have 16 apples and want to share them equally between two people, you can use the halving trick. Since 16 is an even number, dividing it by 2 is as simple as finding half of 16, which is 8. So, each person gets 8 apples.
2. Multiplication Facts as Division Shortcuts
Understanding multiplication is a powerful tool for learning how to divide. This method relies on the idea that division is the inverse of multiplication. If you know your multiplication tables well, you can quickly reverse-engineer them to solve division problems.
Example: Suppose you’re faced with the division problem 63 ÷ 7. If you remember that 7 times 9 equals 63, then you can quickly figure out that 63 divided by 7 is 9. This shows how multiplication facts serve as math division tricks, making division for kids much simpler.

3. The ’10s’, ‘100s’, and ‘1000s’ Trick
Dividing large numbers by 10, 100, or 1000 can seem daunting, but there’s a straightforward trick: moving the decimal point. This is one of the most practical ways to divide large numbers without getting bogged down in complex calculations.
Example: If you need to divide 1,000 by 100, instead of working through the problem the long way, you can simply move the decimal point two places to the left (since you’re dividing by 100). So, 1,000 becomes 10.00, and when you remove the extra zeros, you’re left with 10. This trick demonstrates the easiest way to divide large numbers, making it a favorite among division math tricks.
4. The ‘Doubling and Halving’ Trick
This trick is an easy way to do division, especially when dealing with larger numbers that might initially seem intimidating. The idea is to simplify the division problem by doubling one number and halving the other. This works because the overall value of the problem doesn’t change, just the numbers you’re working with.
Example: Divide 80 by 4 using the ‘Doubling and Halving’ Trick
Apply the Trick:
Double the divisor: Doubling 4 gives you 8.
Halve the dividend: Halving 80 gives you 40.
Revised Problem: Now, instead of dividing 80 by 4, you divide 40 by 8.
Solution:
40÷8=5
This method simplifies calculations, especially when dealing with more complex numbers. By doubling one number and halving the other, you can sometimes make the numbers more manageable without changing the result of the division.
5. Chunking Method
The chunking method is an easy division method that breaks down dividing large numbers into more manageable steps. This method involves subtracting large chunks of multiples of the divisor from the dividend until you reach zero or a remainder smaller than the divisor.
Example: To divide 154 by 7 using the chunking method, start by seeing how many times 7 can fit into 154 in large chunks. You know that 7 times 10 is 70, so you can subtract 70 twice from 154 (140), leaving you with 14. Then, you see that 7 fits into 14 exactly 2 times. Add up all the times you subtracted 7, and you get 22. So, 154 divided by 7 is 22.
6. Skip Counting to Find Quotients
Skip counting is a visual and practical way to solve simple division problems, making it an excellent strategy for kids. It involves counting by the divisor until you reach the dividend. This method is particularly useful for visual learners and can be done with fingers, drawings, or counters.
Example: If you’re trying to divide 24 by 3, you start counting by 3s: 3, 6, 9, 12, 15, 18, 21, 24. Count how many steps you took to reach 24, which in this case is 8. Therefore, 24 divided by 3 equals 8.
7. Reciprocals and Inverse Operations
Understanding reciprocals, and inverse operations are some of the math division tricks that can simplify division, especially as kids start dealing with fractions and more complex numbers. The reciprocal of a number is simply 1 divided by that number, and using it turns division into multiplication, which many students find easier.
Example: If you need to divide 1 by 2 (which is written as 1 ÷ 2), you can multiply 1 by the reciprocal of 2 instead. The reciprocal of 2 is 1/2, so you do 1 × 1/2, which equals 1/2. This approach makes it an easy way to divide, especially when working with fractions, by converting division problems into multiplication ones.

8. Cross-Division Method
The cross-division method, also known as simplification before division, is a handy trick for reducing larger numbers before dividing. This method is particularly useful when the dividend and divisor share a common factor. By simplifying the numbers first, the division becomes much easier.
Example: Suppose you want to divide 48 by 6. You notice that both numbers are divisible by 6. You can simplify 48 divided by 6 to 8 divided by 1 (since 48 ÷ 6 = 8 and 6 ÷ 6 = 1). Your division problem is significantly simpler: 8 divided by 1, which obviously equals 8. This method is a great math division trick because it reduces the complexity of the problem before you even start the actual division.
Common Challenges Kids Face When Learning Division
Learning division can be tricky for many kids. As they navigate the world of mathematics, they encounter several common challenges that can make understanding how to divide overwhelming. Here’s some of these hurdles:
- Grasping the basic idea behind division math problems can be tough. Kids often struggle with the concept that division essentially shares or groups numbers in equal parts.
- A strong foundation in multiplication is crucial to learn division effectively. Many children find it hard to recall multiplication facts, directly impacting their ability to solve division problems.
- When division for kids moves beyond exact answers, the concept of remainders can be confusing. Understanding what to do with the leftover numbers and how they fit into the context of a problem is a common challenge.
- Applying division to solve word problems adds another layer of difficulty. Kids must first decipher what the question is asking before they can even begin to apply their division skills.
- The process of long division, with its multiple steps, can be particularly daunting. Remembering the order of operations and where to write each number requires practice and patience.
- As division problems increase in complexity, so does the intimidation factor. Kids often feel overwhelmed when faced with dividing large numbers, unsure of how to start.
