Update: Kiddo’s learning binary led to bedtime stories being partially replaced by a discussion on how number systems work, binary and hex, and how Daddy used to pass notes encoded in base 3 to his best friend in middle school.

Kiddo surprised me today by learning how to count in binary from a library book. I’d checked out the book for her, but I wasn’t expecting such an immediate pay off. I’m skeptical of the “kids gotta learn CS” agenda, but I’m also proud of her when she does.

I got to teach counting in binary today, and it might be one of my favorite things to teach. Not every day you get to deconstruct and reconstruct your students’ understanding of numbers.
