Understanding Multi-step Word Problems in Grade 3
Multi-step word problems are complex questions that necessitate more than one mathematical operation or procedure to find the answer. Unlike single-step problems, which involve only one operation (e.g., adding two numbers), multi-step problems require students to interpret the problem, identify the relevant information, decide on the order of operations, and perform calculations accordingly. For third graders, mastering these problems involves developing a clear strategy, understanding key vocabulary, and practicing diverse problem types.

Why Are Multi-step Word Problems Important?
1. Develop Critical Thinking Skills
Multi-step problems push students to analyze the problem carefully, determine what is being asked, and decide the sequence of operations. This process helps develop critical thinking and decision-making skills.
2. Reinforce Mathematical Concepts
These problems integrate multiple operations, reinforcing students’ understanding of addition, subtraction, multiplication, and division, as well as the relationships among these operations.
3. Prepare for Future Math Topics
Solving multi-step problems builds a strong foundation for algebra, fractions, and other advanced topics encountered in higher grades.
4. Encourage Real-World Application
Many multi-step problems mimic real-life scenarios—such as shopping, sharing, or measuring—making math relevant and meaningful for students.

Components of Multi-step Word Problems
To effectively solve multi-step word problems, students need to recognize and understand several key components:
1. Read Carefully
Understanding the problem is crucial. Students should read the problem multiple times to grasp the details.
2. Identify Important Information
Highlight or underline essential data—numbers, units, or keywords that indicate operations.
3. Determine What is Being Asked
Clarify the question's goal: Are they finding a total, difference, or amount remaining?
4. Decide on the Operations Needed
Determine which mathematical operations are required and in what order.
5. Plan and Execute Steps
Break down the problem into manageable steps, solve each, and then combine results.
6. Check the Reasonableness
Review calculations and verify answers to ensure they make sense within the context.

Types of Multi-step Word Problems Suitable for Grade 3
Third graders encounter various types of multi-step problems. Here are common examples:
1. Addition and Subtraction Combined
Example: Sarah has 45 candies. She gives 12 candies to her friend and then buys 20 more candies. How many candies does she have now?
2. Multiplication and Addition/Subtraction
Example: A box has 6 rows of apples with 4 apples in each row. If 3 apples are taken out, how many apples are left?
3. Division and Addition/Subtraction
Example: There are 24 cookies shared equally among 4 children. After each child gets their share, 6 cookies are left. How many cookies did each child receive?
4. Multi-operation Problems
Example: Tom has 3 packs of stickers, each containing 10 stickers. He gives away 8 stickers to his friend and then buys 5 more stickers. How many stickers does Tom have now?

Sample Multi-step Word Problems with Solutions
Providing students with worked examples helps them understand how to approach multi-step problems.
Problem 1:
Emma has 12 pencils. She buys 8 more pencils and then gives 5 pencils to her friend. How many pencils does Emma have now?
Solution:
- Step 1: Add the pencils Emma bought to her initial amount: 12 + 8 = 20.
- Step 2: Subtract the pencils given away: 20 - 5 = 15.
- Answer: Emma has 15 pencils now.
Problem 2:
A bakery made 48 cookies in the morning. In the afternoon, they made 36 more cookies. If they sold 50 cookies during the day, how many cookies are left?
Solution:
- Step 1: Find total cookies made: 48 + 36 = 84.
- Step 2: Subtract cookies sold: 84 - 50 = 34.
- Answer: There are 34 cookies left.
Problem 3:
Liam has 3 packs of marbles. Each pack contains 12 marbles. He gives 9 marbles to his brother. How many marbles does Liam have left?
Solution:
- Step 1: Find total marbles: 3 × 12 = 36.
- Step 2: Subtract marbles given away: 36 - 9 = 27.
- Answer: Liam has 27 marbles remaining.
