Detailed Explanation of Subtraction Word Problems – Up to 20 🧮➖

When you are solving subtraction word problems with numbers up to 20, it is important to follow some easy steps. This helps you understand what the problem is asking and find the answer step by step.

Step 1: Read the Problem Carefully 👓📖

First, read the story or problem slowly. Make sure you understand what is happening. Look for words like “left,” “how many more,” “take away,” or “leftover.” These words tell you that you need to subtract.

Step 2: Find the Important Numbers 🔢🔍

Next, find the numbers that the problem talks about. These are usually the amounts you start with and how many are taken away or used. For example, if the problem says, “There are 15 apples, and 7 are eaten,” the numbers are 15 and 7.

Step 3: Write the Subtraction Sentence ✍️➖

Now, use the numbers to write a subtraction sentence. This is like a number sentence that shows the problem. For example, 15 – 7 = ___. The first number is the big number or starting amount, the minus sign (–) means take away, and the second number is how many you are taking away.

Step 4: Solve the Problem 🧠✅

Use number facts or counting back to find the answer. You can count backwards on your fingers, a number line, or use objects like counters or blocks to help. For 15 – 7, you count back 7 from 15 to find the answer, which is 8.

Example Word Problem 1 ✏️

Anna has 12 pencils. She gives 5 pencils to her friend. How many pencils does Anna have left?

  • Read: Anna starts with 12 pencils. She gives 5 to her friend.
  • Numbers: 12 and 5
  • Subtraction sentence: 12 – 5 = ___
  • Solve: 12 take away 5 is 7. Anna has 7 pencils left.

Example Word Problem 2 🎈

There are 20 balloons at a party. 8 balloons popped. How many balloons are still there?

  • Read: Start with 20 balloons. 8 popped (taken away).
  • Numbers: 20 and 8
  • Subtraction sentence: 20 – 8 = ___
  • Solve: 20 take away 8 is 12. There are 12 balloons left.

Tips to Remember 💡📋

  • Look for words that mean subtraction like “left,” “take away,” or “how many more.”
  • Always start with the bigger number in your subtraction sentence.
  • Use objects or drawings to help if you find it tricky.

By following these steps, you can solve subtraction word problems with numbers up to 20 very easily! Keep practising and you will get even better.
