# Addition

## Overview

**Addition** gives the **total value** of two or more amounts.

It is the action of adding something to something else.

Let’s take a closer look at the example above.

There are **five** fingers on the first hand and **two** fingers on the second hand.

We can **ADD** them by joining the two amounts together.

This will give us the total number of fingers.

When we ADD **5 plus 2**, we have **7** in all.

We say: FIVE plus TWO equals SEVEN.

We write it like this: **5 + 2 = 7**

Here’s another example.

In this problem, we are joining together two groups of birds.

We are **ADDING** them together.

This will give us the total number of birds.

When we ADD **1 plus 2**, we have** 3** in all.

We say: ONE plus TWO equals THREE.

We write it like this: **1 + 2 = 3**

Let’s take a look at another example with numbers.

This time, we are joining the numbers **5** and **3**.

These numbers are known as **ADDENDS**.

**Addends are the amounts that will be joined together.**

This problem reads as **5 + 3 = 8**.

When the ADDEND **5** is joined with the ADDEND **3**, we get a SUM of **8**.

**SUM** is used to describe the total amount.

There are many different words that are used to describe addition. For example, we can JOIN two amounts together to find the **TOTAL**. Here are several other examples:

Knowing these **keywords** will help you understand that in order to solve the problem, you must **add**. You might see these keywords in math story problems.

In the problem, the fish are being joined together. The key words are **MORE** and **SUM**. This helps tell us that we need to **ADD**.

**TWO** fish joined with **SIX** fish will give us the correct SUM.

**2 + 6 = 8 fish**

There are many strategies you can use to help you add correctly. We will learn about these in other lessons.
