Solving word problems involving multiplication is a step-by-step process. Here’s how to do it:

  1. Read the Problem Carefully: Start by reading the word problem carefully to understand the situation. Pay attention to any numbers, quantities, or relationships mentioned in the problem.
  2. Identify What’s Asked: Determine what the problem is asking you to find. This will be your “goal” or “unknown” in the problem.
  3. Identify What You Know: Identify the information provided in the problem. This may include numbers, quantities, or other relevant details. List them, and if needed, assign variables to unknown quantities.
  4. Choose the Correct Operation: In multiplication word problems, you will typically use the multiplication operation. Determine which quantities need to be multiplied together to solve the problem.
  5. Write an Equation: Create an equation that represents the problem. This equation will involve the quantities you identified in step 3 and the operation you chose in step 4.
  6. Solve the Equation: Use your equation to find the solution to the problem. Perform the multiplication operation to calculate the answer.
  7. Check Your Answer: After finding the solution, read the problem again to make sure your answer makes sense in the context of the problem. Ensure that you addressed what was asked.
  8. Present Your Answer: Write or state your answer clearly, including any necessary units of measurement.

Here’s an example:

Here’s an example:

Word Problem: If Sarah has 4 boxes, and each box contains 6 apples, how many apples does she have in total?


  1. Read the problem.
  2. Identify what’s asked: Find the total number of apples.
  3. Identify what you know: Sarah has 4 boxes, and each box contains 6 apples. You can assign variables: Let A represent the total number of apples.
  4. Choose the correct operation: You will use multiplication (4 boxes × 6 apples per box).
  5. Write an equation: A = 4 × 6
  6. Solve the equation: A = 24
  7. Check your answer: In the context of the problem, it makes sense that Sarah has 24 apples.
  8. Present your answer: Sarah has 24 apples in total.

Remember that practice is key to improving your ability to solve multiplication word problems. Start with simpler problems and gradually tackle more complex ones as you become more comfortable with the process.

Applying multiplication skills to real-life situations is essential because it helps us solve practical problems and make sense of everyday scenarios. Here’s a simplified explanation for primary students:

  1. Shopping: When you go shopping with your parents, you can use multiplication to calculate the total cost. For example, if you want to buy 3 toys, and each toy costs ₦5, you can multiply 3 by 5 to find out how much money you need: 3 x 5 = ₦15.
  2. Sharing Treats: Let’s say you have 2 candy bars, and you want to share them with 4 friends. To figure out how many candy bars each friend gets, you can use multiplication. It’s like dividing, but in a fun way. So, you can say, “2 candy bars for 4 friends means 2 x 4 = 8 pieces of candy, and we share them equally, so each friend gets 8 ÷ 4 = 2 pieces.”
  3. Gardening: If you have a garden and want to plant flowers in rows, you can use multiplication to find out how many flowers you need. For example, if you have 4 rows, and you want to plant 6 flowers in each row, you can multiply: 4 rows x 6 flowers = 24 flowers in total.
  4. Measuring Ingredients: In the kitchen, when you’re helping your mom or dad bake a cake, you may need to use multiplication. If the recipe says you need to add 3 cups of flour and you want to make 2 cakes, you can multiply 3 cups x 2 cakes = 6 cups of flour.
  5. Time Calculation: Multiplication is also handy for telling time. If you have to wait for 3 hours before your favorite TV show starts, and you want to know when it will be on, you can add or multiply. To find the time, add 3 hours to the current time. For example, if it’s 5 PM now, your show will be on at 5 PM + 3 hours = 8 PM.

By using multiplication in these real-life situations, you can solve problems, make decisions, and understand the world around you better. It’s like having a superpower that helps you make sense of numbers and solve everyday challenges! 😊🌟
