**Objective:**

To introduce the concept of addition to students in Year 1 and help them understand the basic principles of adding numbers.

**Engagement Activity:**

Before diving into the rules of addition, let's start by playing a fun game. We will split the class into two groups and do a quick addition race. Each group will have a set of candies, and the goal is to add up the number of candies within the given time. The team that adds the most candies correctly wins the game.

**Discussion:**

Addition is the mathematical operation of combining two or more numbers to get a total sum. The symbol used to represent addition is "+." Adding numbers is easy if we know the basics of addition rules.

Some of the rules include:

- When we add two numbers, the order of the numbers does not matter.
- The total sum of the numbers is called the "sum."
- Addition of zero to any number results in the same number.

**Demonstration:**

We'll conduct a quick demonstration to understand the concept of adding numbers. Let's take the example of adding two numbers together, 2 and 3.

`2`

- 3

5

We start by aligning the numbers vertically and adding the ones' column first. In this case, 2 plus 3 equals 5. We then carry over the tens' place to the next column.

Once the demonstration is over, we'll give students some addition problems to solve in pairs. We'll walk around and assist students as needed.

That's it for our introduction to addition lesson! Remember, addition is all about combining numbers to get a sum, and it's a fun and easy operation to master. Happy adding!
