What is it?

Adding to Make 5 means finding different pairs of numbers that, when put together, give you a total of 5. It helps us understand how numbers combine to form a specific sum.

Simple Example

Quick Example

Imagine you have 3 ladoos. How many more ladoos do you need to have a total of 5 ladoos? You need 2 more, because 3 + 2 = 5.

Worked Example

Step-by-Step

Let's find one way to add numbers to make 5.

Step 1: Start with the number 1.
---
Step 2: Think, '1 plus what number equals 5?'
---
Step 3: You can count up from 1 to 5: 1... (2, 3, 4, 5). You counted 4 numbers.
---
Step 4: So, 1 + 4 = 5.

Answer: One way to make 5 is 1 + 4.

Why It Matters

Understanding how numbers combine is fundamental to all of mathematics. This skill is used by shopkeepers to calculate change, by engineers designing structures, and even by scientists analysing data. It's the base for more complex calculations in subjects like algebra and geometry.

Common Mistakes

MISTAKE: Only thinking of 2 + 3 as the only way to make 5. | CORRECTION: Remember that 1 + 4, 0 + 5, and even 5 + 0 are also valid ways to make 5. Explore all possibilities!

MISTAKE: Forgetting that the order of numbers doesn't change the sum (e.g., 2 + 3 is the same as 3 + 2). | CORRECTION: Understand that addition is 'commutative'. This means 2 + 3 = 5 and 3 + 2 = 5 are the same 'pair' of numbers making 5.

MISTAKE: Confusing addition with subtraction or multiplication. | CORRECTION: Remember that 'adding' means putting numbers together to get a larger total (or the same total if adding zero).

Practice Questions

Try It Yourself

QUESTION: If you have 4 cricket balls, how many more do you need to have a total of 5? | ANSWER: 1

QUESTION: Can you use the number 0 to make 5? If yes, what number do you add to 0? | ANSWER: Yes, 0 + 5 = 5

QUESTION: Rina has some pencils. Her friend gives her 3 more pencils, and now Rina has 5 pencils in total. How many pencils did Rina have to begin with? | ANSWER: 2 pencils (because 2 + 3 = 5)

MCQ

Quick Quiz

Which of these pairs of numbers adds up to 5?

1 and 3

2 and 2

1 and 4

0 and 4

The Correct Answer Is:

1 + 4 equals 5. Options A, B, and D result in sums of 4, 4, and 4 respectively, not 5.

Real World Connection

In the Real World

When you're helping your parents count change at a shop, you often do this! If an item costs 5 rupees and you give the shopkeeper 10 rupees, you quickly calculate that 5 more rupees are needed to make 10 (5 + 5 = 10), so you expect 5 rupees back. Or, when planning to share 5 pieces of mithai among your friends, you decide who gets how many to make sure the total is 5.
