Why Are Decimals So Confusing for Students?

Every student at one time or another asks, “Why are decimals so tricky?” It’s a question that is repeated throughout every class. I get it. Decimals can be a bizarre mix of fractions and whole numbers and that’s why they’re difficult to comprehend.

I remember going to class and trying to get my head around the tiny dots of numbers. But here’s the truth: decimals are actually extremely simple when you break them into pieces. It’s not a secret, but it does require time and practice.

What Are Decimals?

Decimals are numbers with the appearance of a “dot” (called a decimal point) to distinguish entire numbers and fractions. Consider decimals in this way as a method of expressing fractions, but in a simpler, faster format.

For instance, 0.5 is the decimal version of 1/2.

3.75 is the equivalent of 3.75, which means you’ve got three whole numbers and 75/100 for the fractional part.

How Do Decimals Work?

Difference Between Decimals and Whole Numbers

The whole numbers are fairly simple: 1 2 3, etc. But decimals? They’re the tiny bits of numbers in between these total numbers. For example, 2.5 lives between 2 and 3.

Understanding Decimal Places

Let’s zoom in on decimal places.

• The number just to the right left on the decimal point indicates how tiny these pieces of wood are.
• The number that is the first after that decimal number is 10th spot.
• This is also the hundredth spot.

Thus, if you’ve got 0.3, that’s 3 tenths. If you have 0.35, you’ve got 3 tenths and 5 hundredths.

Why Learning Decimals Matters

This is the truth: decimals appear throughout our lives. From budgeting and shopping to measurements and scores in sports, there will be decimals everywhere.

Imagine buying something on PS2.99. Those 99p? It’s a decimal. Learning to work with decimals will help you better understand the concepts, make math less intimidating, and provide you with the ability to use it for the rest of your life.

Common Struggles Students Face with Decimals

I’ve been there, and I’ve heard pupils complain of decimals as well. Here are some of the biggest problems I hear frequently about:

• In the process of forgetting how to line decimals when subtracting or adding.
• Mixing decimal numbers (e.g., mixing up hundredths and tenths).
• Rounding wrongly and causing the world a mess.
• Problems with multiplying decimals and then moving the decimal point to the wrong spot.

Top Tips for Learning Decimals Easily

Do you want you to learn how to use decimals as the pros? Here are some tips that helped me, and I’m confident they’ll benefit you too.

Practice Rounding Decimals

• TIP 1: Take a look at the digit on the right of the place you’re rounding.
• TIP 2 Tip 2: If the number is five or more and you’re not sure, then just round up. If it’s less than 5, you can round it down.

Example:
If you’re looking at the rounding of 4.567 to the nearest hundredth, take a look at the 3rd decimal point (7). Because 7 is higher than 5 and 5, you’ll need to increase it by 4.57.

Visualize using the use of Number Lines

• Tips 3: Utilize a numbers line to find out where decimals reside in between numbers that are whole.
• TIP 4: Draw where your decimal will fall in the ruler between the numbers 0 and 1.

Learn to Add and Subtract Decimals

• TIP 5: Be sure to align the decimal point on both sides prior to making any addition or subtraction.
• TIP 6 Tip 6: Fill in any empty spaces by using zeros to prevent confusion.

Example:
If you are adding 4.56 + 1.7, it helps to write 1.7 as 1.70.

Multiplying and Dividing Decimals

• Tips 7 Don’t pay attention to decimals when you first multiply. Simply multiply the numbers like there was no decimal.
• Tips 8 After multiplying, count the total number of decimal places in both numbers. Then insert the decimal point into.

Example:
2.5 x 3.6, multiply 25 by 36 first, and then put the decimal back in such a way that you get 90.0.

• TIP 9 for dividing: shift the decimal mark in the divisor towards the right until it’s a complete number. Repeat the process for the dividend.

Real-Life Examples of Decimals

Shopping

You’ve purchased PS10 You’re purchasing two items. The first is PS3.45, and the second one is PS6.55. When you add them all up, you’ll end up with PS10.00. If you didn’t have decimals in your head, you’d get lost at the check-out!

Cooking

Recipes sometimes call for decimals. For example, if you’re making a cake and you need 1.75 cups of flour, it’s 1 3/4 cups. Decimals help you be exact.

How to Make Decimals Less Intimidating

• Tip 10: Treat decimals like fractions–it’s just a different language.
• Tips 11: Start small and try to master the basics of questions.
• Tips 12 Utilize visuals such as grids or pie charts to determine what decimals mean.

The more you do it, the more you’ll be able to master it. Don’t forget that decimals don’t exist to fool you. They’re just numbers that are like any other.

FAQs

What’s the most efficient way to keep track of decimal numbers?

I prefer to think of it as a form of money. The first position following the decimal is 10ths, similar to the 10p equals one tenth of one pound. The second position can be described as hundredths, as one penny equals one hundredth of the pounds.

What do I need to know about how it is appropriate to round decimals?

When you round, take a look at the number right next to the area you’d like to round. When it’s 5 or more, then round it up. In the event that the number is less than 4, you can round it down.

Why do decimals matter in real life?

Decimals are everywhere: money measurement, percentages, and measurements. When you’re cooking, shopping, or playing sports, decimals help you find the perfect answer quickly.

What’s the accurate method to learn decimals?

Make use of real-world examples such as shopping amounts or measurements of recipes. Additionally, you can play the online game, which focuses on decimals. They can make learning enjoyable and less anxiety-inducing.

Tackling Decimals with Confidence

At the time of the day, the ability to comprehend decimals requires practice and patience. Do not stress about them.

Start small, follow the suggestions here, and in no time decimals will seem just as natural as numbers in whole. When you’re rounding up prices or baking the best cake, you can be set. Students decimals do not have to be frightening. Accept them, and you’ll be ready for the rest of your life.
