The 8 multiplication table can often be a challenging one for many students. However, with the right strategies, this table can become one of the easiest to master. In this article, we'll explore eight incredible multiplication table tricks that can significantly enhance your skills in arithmetic, focusing particularly on multiplying by 8. Let's dive into these techniques and make multiplication by 8 a breeze!
1. The Double and Double Again Method
One of the simplest tricks to remember multiplication by 8 is to understand that 8 is essentially 2 * 4. Here’s how you can use this:
- Double the number you want to multiply by 8.
- Double it once more. That’s it!
📝 Note: This method works because 2 * 4 = 8, so essentially, you’re doubling twice.
2. The Finger Trick
For visual learners, the finger trick might be an excellent technique:
- Hold your hands in front of you with palms facing you.
- Number each finger from left to right (right hand starting from 1 to 5, left hand from 6 to 10).
- To multiply by 8, find the finger representing the number you’re multiplying. Fold down this finger.
- Count the fingers before your folded finger for the tens, and the fingers after for the ones.
✨ Note: This trick not only helps in multiplication but also adds a fun element to learning.
3. Visualizing the 8 Times Table
Visual learners might benefit from seeing the 8 times table as a pattern:
- Multiples of 8 end in an even digit.
- The pattern of these ending digits repeats: 0, 8, 6, 4, 2.
4. Use an Addition Sequence
Here’s a little-known trick:
- Add the same number multiple times: for example, 8*7 = (7+7+7+7+7+7+7+7) which simplifies to (7*4+7*4).
5. The Power of 2
Understanding powers of 2 can make multiplying by 8 intuitive:
- 8 is 23 (two raised to the third power).
- To multiply by 8, you can multiply by 2 three times.
6. The Halving and Doubling Technique
This method involves some mental gymnastics:
- Divide the number by 2 (halve it) and then multiply by 16, which is 2 * 8.
| Number | Halved | Times 16 | Result |
|---|---|---|---|
| 6 | 3 | 3 * 16 = 48 | 48 |
7. Skip Counting
Skip counting is often overlooked:
- Count in 8s: 8, 16, 24, 32, 40, and so on.
8. Memory Aids
Sometimes, creating a story or rhyme helps:
- “When 8 is what you need to multiply, twice and twice again, that’s no lie.”
The Takeaway
Mastering the multiplication table by 8 can seem daunting, but with these eight strategies, it becomes manageable, fun, and even intuitive. Whether you prefer visual aids like the finger trick, logical approaches like using powers of 2, or mnemonic devices, there’s a method for everyone. The key to quick math skills is practice and finding what resonates with your learning style.
Why is the 8 times table considered tricky?
+
The 8 times table often feels challenging because it doesn’t follow a simple linear pattern like other multiplication tables. The ending digits and large numbers can be hard to remember.
How can I make learning the 8 times table fun?
+
Use games, songs, or even dance moves to make learning interactive. The finger trick, for example, adds a playful element to learning.
Are there any tools or apps recommended for practicing the 8 times table?
+
Yes, there are many educational apps like “Multiplication by Mathsy,” “Math Tricks,” or “Times Tables Pro” that offer interactive ways to practice multiplication.
