Students were given a list of about 25-30 exercises. Of these exercises, I only wanted them to do numbers 1-10. Thinking it was clear and detailed enough this way, I simply wrote on the board, “Answer the first 10 questions”. A student raised his hand, and the following disaster happened:

Student: “Mister Karabekian, we only have to do two questions?”

Me: “What does it say on the board?”

Student: “We only do the two?”

Me: “That is the number *ten*”

Student: “Which one?”

The board says “10 Questions”. Student: “we only do two?” Me: “That is the number ten.” Student: “Which one?”

This student was reading in binary.

(That must be it!)

Clearly, this student is thinking in base 2. This student isn’t stupid, he/she is advanced!

So that’s why his essays are always a bunch of zeros and ones!

Maybe he’s a computer. 10 is how you write the number 2 in binary

I hope so!

How do children reach your class not being able to read numbers up to 10?

Which one? This child isn’t reading in binary, he is simply incapable of reading numbers.
