In today's world, where the thirst for convenience and efficiency drives technological innovation, the concept of a "Make A 10 To Add" method has gained prominence. This arithmetic strategy is not just a tool for quick calculations but a fundamental technique that can enhance one's mathematical proficiency. Whether you're a student trying to grasp the basics of number sense or an individual looking for a faster way to handle everyday calculations, understanding how to make a 10 to add can streamline your cognitive processes and boost your mathematical fluency.
What is the Make 10 Strategy? ๐งฎ
<div style="text-align: center;"> <img src="https://tse1.mm.bing.net/th?q=mental+math+strategy" alt="Mental Math Strategy"> </div>
The "Make 10 to Add" strategy is a mental math technique where the goal is to reach the number 10 or a multiple of 10 to simplify addition. This method plays on the fact that most people find it easier to work with numbers close to or centered around 10 due to the structure of our number system. Here's how it typically works:
-
Identify the numbers: When adding two numbers, look for a pair where one number can be broken down to create a 10 with the other.
-
Make 10: Take a part of one number to add to the other, making it 10 or a multiple thereof, like 15, 20, etc.
-
Add the remaining number: Once you have a 10, add any remaining parts to simplify the calculation.
Example:
Suppose you need to add 8 + 6:
- Think: 8 + 2 = 10, so you can take 2 from the 6, making it 4.
- Add: Now you add 10 + 4, which gives you 14.
The Benefits of Using the Make 10 Strategy โ

-
Real-World Applicability: From splitting bills at a restaurant to calculating discounts in shopping, this method has practical uses in daily life.
How to Teach and Learn the Make 10 Strategy ๐
<div style="text-align: center;"> <img src="https://tse1.mm.bing.net/th?q=teaching+math+strategies" alt="Teaching Math Strategies"> </div>
Teaching or learning this strategy can be fun and interactive. Here's how you can approach it:
For Students:
-
Use Physical Manipulatives: Use counters, beads, or blocks to visually demonstrate how numbers can be combined to make 10.
-
Engage in Games: Create games like "Snap to 10" where players race to find pairs that make 10.
-
Practice with Flashcards: Flashcards with addition pairs that add up to 10 can reinforce the concept.
For Self-Learners:
-
Start with Small Numbers: Begin by adding smaller numbers like 3 + 7 or 4 + 6, then progress to larger numbers.
-
Use Online Tools: There are numerous online platforms where you can practice addition through interactive games and exercises.
-
Daily Calculation: Incorporate the strategy in everyday calculations like figuring out change or splitting bills.
Challenges and Limitations โ ๏ธ

While the "Make 10 to Add" strategy is beneficial, it's not without its challenges:
-
Over-Reliance: Becoming overly dependent on this method might hinder learning other mental math strategies or more complex mathematical operations.
-
Complex Numbers: For numbers further from 10, this strategy might not be as straightforward, potentially leading to more steps or confusion.
-
Variability: Not all numbers lend themselves easily to this strategy, requiring adaptations or combining it with other techniques.
<p class="pro-note">๐ Note: Remember, the strategy is most effective when numbers are close to 10, but with practice, you can adjust for larger numbers as well.</p>
Advanced Techniques and Variations ๐

Once you've mastered the basic "Make 10 to Add" method, you can explore more advanced variations:
-
Making 20 or 50: Apply the same principle but aim for multiples of 10 that are more relevant to larger sums or currency calculations.
-
Complementary Addition: Use the strategy to understand subtraction as well by finding the complement to make 10 or 100.
-
Combination with Other Strategies: Combine with number splitting, rounding, or other mental math techniques for even faster calculations.
Practical Applications ๐

Let's look at how this strategy can be applied in practical scenarios:
-
Budgeting: When calculating weekly or monthly expenses, using this method can help track spending more effectively.
-
Time Management: Planning tasks where the total time should not exceed a round figure (like an hour) becomes simpler.
-
Sale Prices: Quickly figure out discounts or sale prices without the need for a calculator.
-
Sharing Expenses: Dividing bills or costs among friends or family members can be made easier and more equitable.
As we've explored, the "Make 10 to Add" strategy is more than just a simple mental math trick. It's a tool that promotes numerical literacy, efficiency, and a deeper understanding of arithmetic. By integrating this strategy into daily life, not only can you perform calculations more rapidly, but you also develop a more intuitive relationship with numbers, which is invaluable in both academic and practical settings.
