Definition

What is it?

Skip counting by tens from any number means you start at a number and then keep adding 10 to it to find the next number in the sequence. It's like taking steps of 10 at a time on the number line, but you don't always start from zero.

Simple Example

Quick Example

Imagine you have 35 rupees in your piggy bank. If you skip count by tens, the next amount you'd have is 35 + 10 = 45 rupees. Then, 45 + 10 = 55 rupees, and so on. You're just adding a '10' each time.

Worked Example

Step-by-Step

Let's skip count by tens starting from 23.
---Step 1: Start with the given number, which is 23.
---Step 2: To find the next number, add 10 to 23. So, 23 + 10 = 33.
---Step 3: To find the third number, add 10 to the previous result (33). So, 33 + 10 = 43.
---Step 4: Continue this pattern. Add 10 to 43. So, 43 + 10 = 53.
---Step 5: Add 10 to 53. So, 53 + 10 = 63.
The sequence when skip counting by tens from 23 is: 23, 33, 43, 53, 63...

Why It Matters

Understanding skip counting by tens helps you quickly calculate totals and understand number patterns, which is super useful in everyday math. It's a foundational skill for careers like accounting, data analysis, and even managing a small business, where quick mental math is a big advantage.

Common Mistakes

MISTAKE: Adding 1 instead of 10, or forgetting to add anything. For example, starting at 17 and writing 18, 19, 20... | CORRECTION: Always remember to add exactly 10 to the previous number to get the next one.

MISTAKE: Only changing the tens digit but not adding correctly, especially when crossing a 'hundreds' boundary (e.g., from 95 to 105, writing 95, 100, 105). | CORRECTION: Treat it as a standard addition problem: 95 + 10 = 105. The ones digit usually stays the same.

MISTAKE: Starting from zero every time, even when the question asks to start from a different number. | CORRECTION: Always begin with the specific 'any number' given in the question, not necessarily zero.

Practice Questions

QUESTION: What are the next three numbers if you skip count by tens starting from 4?
| ANSWER: 14, 24, 34

QUESTION: Complete the sequence: 68, ___, 88, ___, 108
| ANSWER: 78, 98

QUESTION: A shopkeeper starts with 125 packets of biscuits. If he adds 10 packets to his stock every hour, how many packets will he have after 3 hours?
| ANSWER: After 1 hour: 125 + 10 = 135. After 2 hours: 135 + 10 = 145. After 3 hours: 145 + 10 = 155 packets.

MCQ

Quick Quiz

Which sequence shows skip counting by tens starting from 56?

56, 57, 58, 59

56, 66, 76, 86

56, 60, 70, 80

56, 10, 20, 30

The Correct Answer Is:

Option B is correct because each number is found by adding 10 to the previous number (56+10=66, 66+10=76, 76+10=86). Other options add different amounts or start incorrectly.

Real World Connection

In the Real World

When you check your mobile data usage, sometimes it shows how much data you've used in chunks. Or, think about counting money in 10-rupee notes at a bank or a kirana store – you're essentially skip counting by tens to quickly find the total amount.

Key Vocabulary
