ABOUT DOODLE NOTES
All doodle notes are one-page, hand drawn summaries of specific math topics. They tend to be brief overviews, meant to be used as cheat sheets, study guides, classroom posters, anchor charts, or fun handouts for students to color or add to their interactive notebooks.
**Disclaimer: These are done on paper with pen and then scanned--excuse any imperfections. I usually make these notes while in the middle of teaching a unit: they may be missing some information or only include one approach (I might make different versions of the same topic in the future). They are not meant to replace textbooks or teachers. Sometimes I forgo 100% accuracy for summarization (example: sketching a graph, simplifying a complicated topic to terms that might contradict the pure math taught at higher levels), so please keep that in mind when you hand this out to students. That being said, if there is a blatant error please let me know.**
