At the beginning and middle of our exploration into patterns, an experience I like to do with my students is find patterns in nature. The students can take a photo of the pattern they have found in nature (for example stones and leaves they have found and placed into a pattern). Then students would use that pattern they have found and recreate the same pattern or sequence in another way, possibly through sound or letters.
