What Is Addition? A Kid-Friendly Definition

Let's start with a definition of this maths operation that's easy for them to understand!

Addition is a maths operation that involves combining two or more numbers to find a total. The symbol (+) is used to indicate addition, and this is called a plus sign.

Here's an example of addition at work!

In the equation 2 + 3 = 5, the numbers 2 and 3 are added together to get a sum of 5.

Addition Terms

There are plenty of new vocabulary words for your students to learn when introducing addition. Here are some of the terms you will want to start with.

Sum

The sum is the result of adding two or more numbers. It's the solution or answer to an addition problem!

In the equation 2 + 3 = 5, 5 is the sum.

Addend

The numbers being added in an addition equation are called addends.

For example, in the equation 2 + 3 = 5, both 2 and 3 are addends.

Commutative Property

The commutative property states that changing the order of the addends in your addition problem does not change the sum.

For example, 2 + 3 is the same as 3 + 2.

Associative Property

The associative property states that changing the grouping of the addends in your maths problem will not change the sum.

For example, (2 + 3) + 4 is the same as 2 + (3 + 4).

Repeated Addition

Sometimes a math problem involves adding the same number multiple times. We call this repeated addition, and it's a way to find the product of two numbers where one of the numbers is repeated a certain number of times.

Repeated addition is handy for helping students understand multiplication. After all, multiplication can be thought of as repeated addition.

What Is Partial Sums Addition?

If you know what a sum is, you're halfway to understanding partial sums addition! This maths vocabulary term refers to adding two or more numbers by breaking apart the addends and adding the value of the digits in each place value position from right to left.

This handy strategy is great for students when they are first learning to add two or more numbers. Partial sums addition breaks down the process of addition into smaller, more manageable steps.

Let's look at an example.

If you have the 36 + 27 and want to use partial sums addition, you start by determining the value of the digits in the ones place, adding them together, and writing down the sum (6 + 7 = 13).

Next, add the value of the tens place digits together (30 + 20 = 50), and write down the answer under the previous sum. Add together the two partial sums to get your answer, 63.
