Welcome to an exciting way to learn how to convert decimal numbers into binary numbers using a method called the double-dabble or repeated division-by-2 method. Let’s dive into this fun and easy technique!
Before we start, let’s understand what we’re doing. A decimal number is a number we use every day, like 115, and it’s in base 10. A binary number is a number used in computers, like 1110011, and it’s in base 2. Our goal is to change a decimal number into a binary number.
Let’s take the number 115 and convert it to binary using the double-dabble method. Here’s how it works:
Let’s see how this works with 115:
Now, read the remainders from bottom to top: 1110011. So, the binary equivalent of 115 is 1110011.
Try using this method with different numbers to get the hang of it. It’s a great way to understand how computers think and work with numbers!

Thanks for learning with us, and happy encoding!
Challenge your classmates to a race! Each of you will pick a different decimal number and convert it to binary using the double-dabble method. The first one to correctly convert their number wins. This will help you practice the steps and improve your speed.
Create a piece of art using binary numbers. Convert your favorite decimal numbers into binary and use them to design a pattern or picture. This will help you visualize the binary system and see how numbers can create something beautiful.
Work in pairs to create binary code puzzles for each other. Convert a secret message into binary and see if your partner can decode it back into decimal. This will reinforce your understanding of the conversion process and make learning fun.
Create a number line on the classroom wall with both decimal and binary numbers. As you learn new conversions, add them to the line. This visual aid will help you see the relationship between decimal and binary numbers.
Go on a scavenger hunt to find examples of binary numbers in the real world. Look for digital clocks, computers, or anything that uses binary. Share your findings with the class and discuss how binary is used in technology around us.
Sure! Here’s a sanitized version of the YouTube transcript:

Hello and welcome to Tutoring Hour! In this video, I’ll introduce you to an easy method for converting a decimal number into a binary number, known as the double-dabble method or the repeated division method.
Let’s take the number 115 and convert it from base 10 to base 2.
115 divided by 2 is 57. We need to keep track of the remainders at each step, so let’s note the remainder, which is 1.
Dividing 57 by 2 again gives us 28 with a remainder of 1. Now, 28 divided by 2 leaves us with 14 and the remainder is 0.
14 divided by 2 is 7, and the remainder is 0 again. Dividing 7 by 2 gives us 3 with a remainder of 1.
3 divided by 2 is 1 with a remainder of 1.
We’ll write the final quotient 1 along with the remainders from the bottom to the top. The binary equivalent of 115 is 1110011.
We hope this has helped you understand the double-dabble method for converting a decimal number to a binary number. Use this method and start encoding!

Decimal – A number system based on ten, using digits 0 through 9. – In mathematics class, we learned how to convert a binary number into a decimal number.
Binary – A number system that uses only two digits, 0 and 1. – Computers use the binary system to process data efficiently.
Method – A systematic way of doing something, often involving a step-by-step process. – Our teacher showed us a new method to solve quadratic equations.
Convert – To change something into a different form or system. – We need to convert the decimal number 25 into binary for our computer science project.
Number – A mathematical object used to count, measure, and label. – The number 42 is often used as an example in math problems.
Quotient – The result of dividing one number by another. – When you divide 20 by 4, the quotient is 5.
Remainder – The amount left over after division when one number does not divide the other exactly. – In the division of 17 by 3, the quotient is 5 and the remainder is 2.
Divide – To separate into equal parts or groups, often used in arithmetic. – We learned how to divide fractions in today’s math class.
Computers – Electronic devices that process data and perform tasks according to instructions. – Computers can perform millions of calculations per second using binary code.
Practice – The repeated exercise of an activity to improve skill. – To get better at solving algebra problems, you need to practice regularly.
