Addition challenge problems

Stretch confident learners with multi-step and open-ended problems.

Quick answer

Addition challenge problems help you use addition in more complex ways – like solving puzzles, working out real-life situations, or combining more than two numbers to find a total.

Learning outcome

By the end of this page, you will be able to solve addition problems that involve more than one step or that ask you to think carefully about how to use addition in real life. Success signs:
  • You can add up more than two numbers in a problem
  • You can solve word problems that use addition
  • You can find missing numbers in addition problems
  • You can use addition to solve puzzles or real-life challenges

Why this matters

Addition challenge problems help you think more deeply about numbers. These problems are like puzzles that help you become better at maths. They’re useful in school when you have to add more than just two numbers, or when you need to solve tricky word problems. You’ll also use these skills in real life, like when you’re planning a party, counting your pocket money, or working out how much you’ve saved.

How it works

Addition challenge problems are more than just adding two numbers together. They can include:
  • More than two numbers
  • Word problems that need you to understand what to add
  • Missing numbers that you have to find
  • Real-life situations where you need to add in a smart way
To solve these problems:
  1. Read the problem carefully
  2. Find out what numbers you need to add
  3. Use your addition skills to find the total
  4. Check if your answer makes sense

Examples you can see

Let’s look at some examples of addition challenge problems. Example 1: Adding more than two numbers If you have 5 apples, 3 oranges, and 2 bananas, how many pieces of fruit do you have altogether?
  • 5 + 3 + 2 = 10
Example 2: Word problem with a twist You have £8. You buy a toy for £3 and a snack for £2. How much money do you have left?
  • First, add what you spent: £3 + £2 = £5
  • Then, subtract from what you had: £8 - £5 = £3
Example 3: Missing number problem What number makes this sentence true? 7 + ? = 12
  • Think: What number added to 7 makes 12?
  • Answer: 5, because 7 + 5 = 12

Try it as a mini adventure

Adventure: The Treasure Hunt You are going on a treasure hunt! You start with 10 coins. Then, you find 5 more coins in the first chest. Next, you find 3 more coins in the second chest. Finally, you find 2 more coins in the last chest. How many coins do you have now?
  1. Start with: 10 coins
  2. Find 5 more: 10 + 5 = 15 coins
  3. Find 3 more: 15 + 3 = 18 coins
  4. Find 2 more: 18 + 2 = 20 coins
You found a total of 20 coins!

Common mistakes

  • Mistake: Adding numbers in the wrong order or skipping some numbers.
    Why it happens: You might get confused if there are many numbers or if you’re in a hurry.
    Fix: Read the problem slowly, write down each number, and add them one by one.
  • Mistake: Not understanding what the question is asking.
    Why it happens: Word problems can be tricky and have extra information.
    Fix: Circle or underline the numbers and what you need to do.
  • Mistake: Forgetting to check your answer.
    Why it happens: You might be excited to finish and not double-check.
    Fix: Always ask yourself, “Does this answer make sense?”

Parent and carer guide

As a parent or carer, you can help by:
  • Reading the problem together and asking what numbers are involved
  • Encouraging your child to write down each step
  • Helping them check their answer by using a different method
  • Using real-life examples, like shopping or cooking, to make the problem more relatable
  • Letting them explain their thinking to you – this helps them learn better
It’s okay if your child makes a mistake – that’s how they learn! Don’t rush to correct them. Instead, ask questions like, “How did you work that out?” or “Can you try adding them again?”

Practice questions

  1. There are 4 red balloons and 6 blue balloons. How many balloons are there altogether?
  2. Tom had 12 stickers. He gave 3 to his friend and then bought 5 more. How many stickers does he have now?
  3. What number makes this true: 9 + ? = 15?
  4. There are 3 boxes of pencils. The first box has 7 pencils, the second has 5, and the third has 8. How many pencils are there in total?
  5. Amy has 10 books. She gets 4 more for her birthday and then gives 2 away. How many books does she have now?

  1. 4 + 6 = 10
  2. 12 - 3 = 9, then 9 + 5 = 14
  3. 6, because 9 + 6 = 15
  4. 7 + 5 + 8 = 20
  5. 10 + 4 = 14, then 14 - 2 = 12
