What is it?

Skip counting by eights means counting forward by adding 8 each time, instead of counting by ones. It's like taking jumps of 8 on a number line, starting from a number and adding 8 repeatedly.

Simple Example

Quick Example

Imagine you are buying ladoos for a festival, and each box has 8 ladoos. If you buy 1 box, you have 8 ladoos. If you buy 2 boxes, you skip count by 8 and get 16 ladoos (8 + 8). For 3 boxes, you get 24 ladoos (16 + 8).

Worked Example

Step-by-Step

Let's skip count by eights, starting from 0, for five steps.

Step 1: Start with 0.

---

Step 2: Add 8 to the starting number: 0 + 8 = 8.

---

Step 3: Add 8 to the new number: 8 + 8 = 16.

---

Step 4: Add 8 again: 16 + 8 = 24.

---

Step 5: Add 8 one more time: 24 + 8 = 32.

---

The numbers are 0, 8, 16, 24, 32.

Why It Matters

Skip counting by eights helps you understand multiplication tables of 8 quickly. It's a fundamental skill for faster mental math and problem-solving. Engineers use this concept to count components, and shopkeepers use it to quickly total items in groups.

Common Mistakes

MISTAKE: Adding a different number instead of 8 in some steps. For example, 8, 16, 20, 28... | CORRECTION: Always add exactly 8 to the previous number to maintain the skip counting pattern.

MISTAKE: Starting from 1 and then adding 8. For example, 1, 9, 17... | CORRECTION: Pay attention to the starting number given. If no starting number is given, usually assume 0 or 8 (if counting the 8 times table).

MISTAKE: Forgetting to add 8 and just writing down random numbers. | CORRECTION: Use your fingers or draw small dots to help you count 8 steps forward from the previous number if you find it difficult to do mentally.

Practice Questions

Try It Yourself

QUESTION: What are the next three numbers if you skip count by eights starting from 40? | ANSWER: 48, 56, 64

QUESTION: If a bus carries 8 passengers per trip, how many passengers will it carry in 6 trips? (Hint: Skip count by eights 6 times) | ANSWER: 48 passengers

QUESTION: A gardener plants flower pots in rows. Each row has 8 pots. If he has already planted 5 rows, how many pots will he have after planting 3 more rows? | ANSWER: 64 pots (5 rows * 8 pots/row = 40 pots. Then 3 more rows means 40 + 8 + 8 + 8 = 64 pots)

MCQ

Quick Quiz

Which of these sequences shows skip counting by eights?

10, 18, 26, 34

8, 16, 24, 32

8, 10, 12, 14

1, 8, 16, 24

The Correct Answer Is:

Option B correctly shows adding 8 each time (8+8=16, 16+8=24, 24+8=32). Options A, C, and D do not consistently add 8.

Real World Connection

In the Real World

In cricket, if a batsman hits only fours and eights (by running 4 and hitting 4), you might skip count by eights to quickly calculate their score if they only hit boundaries of 8 runs. Also, when counting items in a large package that contains groups of 8, like 8 pencils per box, skip counting helps to find the total quickly.
