# Bending Binary

### Welcome to Bending Binary

Get a solid foundation in binary, the numbering system at the core of how computers "think".

## Together you'll learn:

• What binary is and what it can be used for
• How to convert a decimal number into binary
• How to convert words and names into binary using ASCII
• How to convert binary numbers into hexadecimal
• How to write and decode your own secret message using binary and hexadecimal

## Module #1 - Intro into Binary

In this module, you’ll introduce your learner to the basics of the binary system and how computers use it to “think”. Your learner will get hands-on practice counting and converting numbers 1 to 20 into binary.

Estimated time: 5 minutes

## Module #2 - Building numbers with blocks

Next, you and your learner will discover how to convert larger numbers into binary using the block method. Test your new binary skills with a short quiz at the end.

Estimated time: 10 minutes

## Module #3 - ASCII

Now that we have our numbers down, it’s time to try out some letters. In this module, your learner will practice converting letters into binary. By the end, they will learn to spell words and their name using the same ASCII standard used in computers.

Estimated time: 15 minutes

## Module #4 - Hexadecimal Numbering System

Binary can get pretty long, so next you’ll introduce your learner to the hexadecimal numbering system, which lets you express large numbers in a smaller space. Your learner will practice breaking up binary into smaller pieces called bits, nibbles, and bytes (yum!) and then converting them into hexadecimal.

Estimated time: 15 minutes

## Module #5 - Final Challenge

Now that your learner has their binary down, it’s time to put them to the test! Your learner will test their new skills by writing a secret message in binary and hexadecimal and seeing if someone else can decode it (maybe it will be you!)

Estimated time: 10 minutes
