Definition Addition is the process of putting objects or numbers together. It is the manner of combining addends and determining their total. Addition is one of the four basic fundamental math operations. It is the extension of the learned concepts from counting and recognizing numbers. Once a learner has been able to recognize and count objects, it is just right to advance their math skills by teaching them how to add. Since it is one of the foundations of learning mathematics, addition is being taught as early as Kindergarten. At this level, learners are given tangible objects to help them visualize and experience what addition is in real life. Starting from addition within 10, the range of numbers being considered gets higher as the child progresses to the succeeding levels. In general, addition is being introduced in early grades, reinforced in 3rd to 4th grades, mastered in 5th to 6th grades, and applied in 7th to 9th grades.
Importance of the Topic Obviously, addition is one of the mathematics skills that a learner must master and apply. It is an important lesson that the children should learn because some topics in the succeeding levels are related to addition. For example, multiplication is actually a repeated process of addition. If a child finds it difficult to add numbers, it will also be a struggle for him to learn multiplication. Other than that, when performing subtraction of numbers, you can actually validate if your answer is correct once you got the sum of the difference and the subtrahend equal to minuend.
Addition is also vital in understanding operations involving fractions, decimals, algebraic expressions, polynomials, functions, etc. In general, addition helps the learners to see the relationship of two quantities, provides them opportunity to develop their number sense skills, numerical operations, and fluency in doing computations. It is a powerful foundational concept in mathematics, with applications to many problem situations and connections to many other topics.
Application of the Learned Topic in Life Addition is useful in various life situations. Addition helps to solve money-related problems: it is needed to determine the total amount of money you have in your wallet or bank; to quantify the total bill of a lunch or dinner; to estimate the amount of the items you bought in the supermarket, etc. It can also be applied in school-related situations such as indicating the total number of chairs needed inside the auditorium, the sum of the numbers of boys and girls in a particular level, the overall total of a school population, and many more.
