Detailed Explanation of Addition and Subtraction Word Problems – Up to 100 🧮

When you solve addition and subtraction word problems up to 100, it helps to understand what the question is asking. In Year 3, we follow the UK National Curriculum, so you will often see problems that use numbers up to 100. Here are some easy steps and tips to help you work through these problems carefully.

Key Strategies for Addition and Subtraction Word Problems 🔑

1. Read the problem carefully
   Always start by reading the whole problem slowly. Make sure you understand what is happening and which numbers are important.
2. Identify the operation
   Decide if you need to add or subtract. Look for keywords:
   • Add: words like “total,” “altogether,” “more,” “combined”
   • Subtract: words like “left,” “difference,” “leftover,” “fewer”
3. Pick out the numbers
   Find the numbers in the problem that you will use to add or subtract.
4. Write a number sentence
   Turn the problem into a calculation using + or –. For example, if the problem says, “Sara has 45 marbles and buys 32 more,” the number sentence is 45 + 32.
5. Solve the calculation
   Use your addition or subtraction skills to find the answer. You can use a number line, draw pictures, or count on and back to help.
6. Check your answer
   Read the problem again and see if your answer makes sense.

Example 1: Addition Word Problem ➕

Problem: Tom has 27 stickers. He finds 38 more stickers. How many stickers does Tom have now?

• Step 1: Read carefully – Tom wants to know the total number of stickers.
• Step 2: Keywords – “more” means add.
• Step 3: Numbers – 27 and 38.
• Step 4: Number sentence: 27 + 38 = ?
• Step 5: Solve – 27 + 38 = 65
• Step 6: Check – It makes sense that Tom now has 65 stickers in total.

Example 2: Subtraction Word Problem ➖

Problem: Lily had 90 sweets. She gave 45 sweets to her friends. How many sweets does she have left?

• Step 1: Read carefully – Lily wants to know what is left.
• Step 2: Keywords – “gave” and “left” mean subtract.
• Step 3: Numbers – 90 and 45.
• Step 4: Number sentence: 90 – 45 = ?
• Step 5: Solve – 90 – 45 = 45
• Step 6: Check – Lily has 45 sweets left after giving some away.

Tips to Remember 💡

• Use a number line to count forwards for addition or backwards for subtraction.
• Draw pictures or use objects like counters or cubes to help you see the problem.
• Break bigger numbers into smaller parts you can add or subtract easily (for example, 38 = 30 + 8).
• Always reread the problem to make sure your answer answers the question.
• Practice with different problems to get confident.

Using these strategies will help you solve addition and subtraction word problems up to 100 more easily and accurately! Keep practising, and you’ll get better every day!
