Solved multi-step word problems Grade 4 with explanations

📚 Understanding Multi-Step Word Problems

Multi-step word problems require you to perform more than one operation (addition, subtraction, multiplication, or division) to find the solution. They often involve a combination of these operations, making them a bit more challenging but also more rewarding to solve!

• 🔍 Identify the Problem: Read the problem carefully and determine what it is asking you to find.
• 📝 Plan Your Steps: Decide which operations you need to perform and in what order.
• ➕ Solve Each Step: Perform each operation carefully, one at a time.
• ✅ Check Your Answer: Make sure your answer makes sense in the context of the problem.

🚀 Warm-up (5 mins)

Review basic operations (addition, subtraction, multiplication, division) with simple one-step word problems.

• ➕ Example: Sarah has 5 apples. John gives her 3 more. How many apples does Sarah have in total? (Answer: 5 + 3 = 8 apples)
• ➖ Example: Tom had 10 candies. He ate 4 of them. How many candies does Tom have left? (Answer: 10 - 4 = 6 candies)

🧑‍🏫 Main Instruction

Introduce the concept of multi-step word problems and demonstrate how to break them down into smaller, manageable steps.

• 📖 Example 1: A store sells pencils for $ \$0.25$ each and erasers for $ \$0.15$ each. Lisa buys 3 pencils and 2 erasers. How much does she spend in total?
  1. ✏️ Step 1: Calculate the cost of the pencils: $3 \times \$0.25 = \$0.75$
  2. 🧼 Step 2: Calculate the cost of the erasers: $2 \times \$0.15 = \$0.30$
  3. 💰 Step 3: Add the cost of the pencils and erasers: $ \$0.75 + \$0.30 = \$1.05$
  4. ✅ Answer: Lisa spends $ \$1.05$ in total.
• 📖 Example 2: A baker makes 24 cookies. He sells half of them in the morning and then eats 3 cookies in the afternoon. How many cookies are left?
  1. 🍪 Step 1: Calculate the number of cookies sold: $24 \div 2 = 12$
  2. 🍪 Step 2: Calculate the number of cookies remaining after selling: $24 - 12 = 12$
  3. 😋 Step 3: Subtract the number of cookies eaten: $12 - 3 = 9$
  4. ✅ Answer: There are 9 cookies left.
