## Reflection: Relevance Binary Code - Section 1: Introduction

This may seem like a peculiar choice for codes to focus on, but I chose it for two reasons.  First, it created the most basic of connections between our electricity unit, which used simple lights and motors, to what is happening at the most basic level of a computer chip.  Next, I felt that though binary encoding/decoding is happening deep under the hood of our software and hardware, it is the fundamental language by which they operate, and is important for any programmers to understand.  It turned out to have one more unexpected benefit.  Comparing the base two system of binary to our base ten system actually seemed to help strengthen student understanding of place value.

Why binary?
