Subtraction: Taking Away!

Chapter 6: Subtracting Without Borrowing

When we subtract, we take away from what we have. The rule? Only take what's available in each place — ones from ones, tens from tens!

Riya has a beautiful sticker collection! 🌟

"I have 47 stickers. I want to give 23 stickers to my friend."

Milo tilts his head. "Do we have enough ones to take away?"

Riya checks: "7 ones, and I need to remove 3... Yes! I have enough!"

🧠

Recall: Place Value

Tens stay with tens, ones stay with ones

Just like in addition, we work with each place separately.

I have

47

4 tens + 7 ones

📐

"We can only take away what we have in each place."

💡 The key question: "Do I have enough ones? Do I have enough tens?" In this chapter, the answer is always YES!

Taking Away Ones

Remove loose ones first

38 − 5 = ?

I have 8 ones

Left over

? ones

Do I have enough ones?

✓ Yes! 8 ≥ 5

✓ Always check first: "Do I have enough ones to take away?" If yes, proceed!

Taking Away Tens

Remove whole bundles

48 − 20 = ?

I have 4 tens

4 tens

Take away 2 tens

2 tens

Left over

? tens

Do I have enough tens?

✓ Yes! 4 ≥ 2

💡 Bundles stay as bundles! We remove whole bundles, not individual sticks from inside.

Subtracting Tens AND Ones

Step 1: Check — do we have enough in each place?

Ones: 4 ≥ 3?

✓ Yes!

Tens: 6 ≥ 2?

✓ Yes!

⚠️ This chapter is safe: We always have enough to subtract. No borrowing needed!

Writing Subtraction

The vertical (column) way

We can write subtraction in columns. Ones under ones, tens under tens!

⚠️

"Nothing moves from another place." (No borrowing in this chapter!)

💡 Work column by column: Ones: 4 − 3 = 1. Tens: 6 − 2 = 4.

Find the Missing Number

Early equation sense

One number is hidden! Can you figure out what it is?

47 − ? = 22

💡 Think: "What do I need to take away from 47 to get 22?"

Taking Away Carefully

🌍

Subtraction in Real Life

Taking away is everywhere!

📦

Items from a Box

"The box had 45 crayons. We took out 12. How many are left?"

👧👦

Students Leaving

"38 students were in class. 15 went home. How many stayed?"

💰

Money Spent

"I had ₹56. I spent ₹23. How much do I have now?"

🍎

Eating Snacks

"There were 29 cookies. We ate 16. How many are left?"

💡 Try at home: Count items, remove some, and count again. See subtraction in action!

Questions & Answers

Taking away carefully

What does subtraction mean here?

It means taking a smaller amount out of a bigger one and finding what is left. Both numbers have tens and ones now.

Why do I start with the ones?

So you can see straight away whether the ones are enough. If they are, the whole sum stays simple.

How do I do 58 take away 23?

Ones first. 8 take away 3 is 5. Then tens. 5 tens take away 2 tens is 3 tens. The answer is 35.

Does order matter in subtraction?

Yes, a lot. 58 take away 23 is not the same as 23 take away 58. The bigger amount must come first.

What happens if I subtract zero?

Nothing changes. 47 take away 0 is 47. You removed no things.

What if both numbers are the same?

You are left with zero. 36 take away 36 is 0. Everything was removed.

When is subtraction without regrouping possible?

When the top ones digit is as big as or bigger than the bottom one. Then no ten needs to be opened.

How do I check my answer?

Add your answer back to the number you took away. You should get the number you started with. 35 plus 23 is 58.

⚠️ Common Mistakes to Watch For

Subtracting smaller from larger: Writing 3 − 4 = 1 instead of recognizing this needs borrowing (next chapter).

Mixing places: Taking ones from the tens column or vice versa.

Not checking first: Proceeding without verifying there's enough to subtract.

Order confusion: Writing 45 − 23 but calculating 23 − 45.

🏠 Home Activities

Physical Removal: Start with a pile of objects, remove some, count what's left.

Story Problems: "We had 37 grapes. We ate 12. How many are left?"

Shopping Math: "I had ₹48. I spent ₹25. What do I have now?"

🎯 Signs Child is Ready for Borrowing (Ch. 7)

✓ Confidently subtracts without borrowing

✓ Recognizes when ones digit is too small ("I can't take 7 from 3!")

✓ Understands 1 ten = 10 ones (from place value work)

✓ Asks "What do I do when I don't have enough?"

💜 Why no borrowing yet? Borrowing is introduced in Chapter 7. This chapter builds confidence with "safe" subtraction. Rushing causes confusion and procedural errors. Let children master the "check first" habit!
