# Patterns and Pre-Algebra

Yesterday I was able to get outside and walk around a local park.  While soaking up the sun I started to notice a variety of patterns on the sides of the path.  The patterns changed depending on the vegetation and location.  As I searched for additional patterns I started to find more and and then looked for consistency among the sequences. I took out my phone and started taking pictures of the patterns that I saw thinking that I might use them next school year. After collecting a few I started thinking about how this connects to the math strand of algebra.

Taking the pictures had me thinking of a class I had a few years ago.  I remember reading a district-adopted fourth grade text that introduced pre-algebra to students as patterns and solving for the unknown.  This simple kid-friendly definition was explained to elementary students in a short paragraph. After thoroughly discussing the definition of a pattern (yes, that took time), students took that definition and ran with it.  They started to find patterns (number and otherwise) in and outside of the classroom. If a pattern didn’t seem to exist, students would make a prediction based on the prior sequence.  A completed pattern seemed to make sense and an uncompleted sequence didn’t have meaning.  Students started to put on their “pattern glasses” to identify sequences.  Students would argue whether something was a pattern or not.  I distinctly remember one student saying that to complete the pattern you need to find the missing puzzle piece. These discussions were interesting to observe as students were developing their own rules to the patterns and offering their suggestions to others.
