PEOPLE are not BINARY, COMPUTERS are.
“They are all around you. Every path forks off from another path.” Tortoise said. “One path become 2, 2 become 4, the 8, 16, and so on. After 24 forkings, there are over 16 million different paths.” “Oh! It’s the Power of Two again. But this time it gets bigger instead of smaller.” Laurie said.

- DATA COLLECTION and ANALYSIS: Count and organize beads
- DATA REPRESENTATION: What does each bead represent?
- PROBLEM DECOMPOSITION: Break Byte into Nibble into Bits
- PATTERN RECOGNITION AND ANALYSIS: What patterns do you see in the different letters?
- ABSTRACTION: The template
- ALGORITHM: The steps used to make a binary bracelet.
Motivate students to search “binary” and take them down pathways of interest from computational photography to adding in binary. On to UPC barcodes and QR codes and imagining new inventions that are based on two.
To create Binary Art:
- Watch video on code.org: Unplugged Binary Images Lesson
- Try the really hard Code Studio 4 Binary Art Lesson
- If don’t get IT, go back and complete Code Studio courses 1, 2, and 3
To create Binary Jewelry:
- Watch video on code.org: Unplugged Binary Bracelet Lesson
- Plan your bracelet using the paper bracelet worksheet decoder.
Networking Bag – To create an elastic hair band use stretchable string instead of a pipe cleaner. At right is a sample valentine themed net-work-ing bag. Participates share something about themselves that starts with the letter in their bag. I pass out bags with my business card at presentations as a warm-up. Saves time as teachers have something to do while I am setting up and walking around getting to know the participants. I give them the algorithm – you can download the directions here: Binary Bracelet Code.
Now try again, and again, to come up with your own design idea. It takes lots of failures to learn the technique. Learn from experts online.

I thought … I did … I thought that wasn’t right … I thought to myself to understand what to do … I looked for it … I figured it out …
… “I am going to be a computer scientist.”
REAL-WORLD Fund Raiser – “Make it popular to wear a binary bead bracelet.”
