Maths vocabulary

Mathematics is a language and culture in its own right, and just like any language, it has its own specific and technical vocabulary. Understanding mathematical terms and their relationships is crucial in mastering the fundamental operations: addition, subtraction, multiplication, and division. Teaching these concepts to children not only involves teaching the operations themselves but also the associated vocabulary. Let's delve into how understanding mathematical terms aids in reasoning within each operation.


Addition: Exploring Addends and Sums


Addends + Addend = Sum


Addition is about combining quantities. The numbers we add are called addends, and the result is known as the sum. For instance, 2 + 3 = 5, where 2 and 3 are addends, and 5 is the sum.


How Vocabulary Aids Reasoning: When children understand that changing an addend affects the sum, they grasp the concept better. Adding 1 to an addend means adding 1 to the sum, reinforcing the idea that every change in an addend influences the final outcome.




Subtraction: Understanding Minuends, Subtrahends, and Differences


Minuend - Subtrahend = Difference


Subtraction involves taking away one quantity from another. The starting number is the minuend, the number being subtracted is the subtrahend, and the result is the difference. For instance, 7 - 4 = 3, where 7 is the minuend, 4 is the subtrahend, and 3 is the difference.


How Vocabulary Aids Reasoning: Knowing the terminology helps children understand that when they subtract, they are finding the difference between two numbers. This understanding empowers them to tackle word problems and real-life scenarios.





Multiplication: Embracing Factors and Products


Factor x Factor = Product


Multiplication involves repeated addition or scaling of numbers. The numbers being multiplied are factors, and the result is the product. For example, 2 × 4 = 8, where 2 and 4 are factors, and 8 is the product.


How Vocabulary Aids Reasoning: Doubling a factor and keeping the other factor the same doubles the product. This understanding becomes evident when children comprehend that changing factors in multiplication alters the final product proportionally.





Division: Grasping Dividends, Divisors, and Quotients


Dividend ÷ Divisor = Quotient


Division is the process of sharing or partitioning a quantity into equal parts. The number being divided is the dividend, the number by which it is divided is the divisor, and the result is the quotient. For instance, 10 ÷ 2 = 5, where 10 is the dividend, 2 is the divisor, and 5 is the quotient.


How Vocabulary Aids Reasoning: Understanding the relationship between dividend, divisor, and quotient assists children in interpreting division as the inverse of multiplication. For instance, knowing that 4 ÷ 2 = 2 implies that 2 × 2 = 4. It may also guide children to reasoning that remainders can never be the same as or greater than the divisor.



Mastering mathematical vocabulary lays the foundation for a deeper comprehension of arithmetic. It enables children to reason through problems and develop a stronger mathematical intuition. By embracing these terms, educators and parents can empower young learners to navigate the fascinating world of numbers with confidence and clarity.
