Place Value

✨ Section 1: What Is Place Value?

Place value means the value of a digit depends on where it is in the number.
In Grade 1, we focus on two places:

• 🟩 Tens place (groups of ten)
  
  

• 🟨 Ones place (leftover ones)
  
  

Each digit has a job. Its place tells us how much it’s worth.

🧩 Section 2: How Does Place Value Work?

Let’s look at the number 42:

• The 4 is in the tens place → 4 tens = 40
  
  

• The 2 is in the ones place → 2 ones = 2
  
  

So:
➡️ 42 = 40 + 2

We’re saying: "Four tens and two ones."

🎯 Section 3: Why Should We Learn Place Value?

Place value helps us:

• Read and write numbers correctly
  
  

• Break numbers into parts (tens and ones)
  
  

• Add and subtract more easily
  
  

• Understand how numbers grow
  
  

It also helps in word problems, counting money, and telling time!

📘 Section 4: Place Value Examples

Example 1:

Number: 36

• 3 tens = 30
  
  

• 6 ones = 6
  ✅ 36 = 30 + 6
  
  

Example 2:

Number: 19

• 1 ten = 10
  
  

• 9 ones = 9
  ✅ 19 = 10 + 9
  
  

Example 3:

Number: 70

• 7 tens = 70
  
  

• 0 ones = 0
  ✅ 70 = 70 + 0
  
  

🔍 Section 5: How to Identify Place Value in Any Number

Steps to follow:

1. Look at the number (like 64)
   
   

2. The left digit is the tens place
   
   

3. The right digit is the ones place
   
   

Example: 64

• 6 is in the tens place → 60
  
  

• 4 is in the ones place → 4
  ✅ 64 = 60 + 4
