2-4 Addition Word Problems

Key Concepts

Addition word problems involve using real-life scenarios to add two numbers together. In Grade 1, we focus on simple problems that involve adding two small numbers, such as 2 and 4.

1. Understanding the Problem

The first step in solving an addition word problem is to understand what the problem is asking. Read the problem carefully and identify the two numbers you need to add together.

2. Setting Up the Addition

Once you understand the problem, set up the addition equation. Write the two numbers you need to add, with a plus sign (+) in between them, and an equal sign (=) at the end.

3. Solving the Addition

After setting up the equation, solve the addition. Add the two numbers together to find the total.

4. Writing the Answer

Finally, write the answer to the problem. Make sure to include the units (if any) and check that your answer makes sense in the context of the problem.

Detailed Explanation

Understanding the Problem

For example, consider the problem: "Sarah has 2 apples. She gets 4 more apples. How many apples does she have now?" Here, you need to add 2 and 4 to find the total number of apples.

Setting Up the Addition

Set up the addition equation as follows: 2 + 4 = ?

Solving the Addition

Now, solve the addition: 2 + 4 = 6. Sarah has 6 apples in total.

Writing the Answer

Write the answer as: "Sarah has 6 apples now."

Examples and Analogies

Example 1: Adding Toys

Imagine you have 2 toy cars. Your friend gives you 4 more toy cars. How many toy cars do you have now? Set up the equation: 2 + 4 = 6. You have 6 toy cars in total.

Example 2: Adding Flowers

Suppose you have 2 flowers in a vase. You add 4 more flowers to the vase. How many flowers are in the vase now? Set up the equation: 2 + 4 = 6. There are 6 flowers in the vase.

Analogy: Adding Candies

Think of adding candies. If you have 2 candies and you get 4 more candies, how many candies do you have now? Set up the equation: 2 + 4 = 6. You have 6 candies in total.

Conclusion

Addition word problems help you apply the concept of addition to real-life situations. By understanding the problem, setting up the addition, solving it, and writing the answer, you can successfully solve any simple addition word problem.
