A formula/reference sheet (for geometry, algebra, or trigonometry, for example) can be overwhelming.
- Identify and focus on the big key ideas of the sheet, with which we need to become fluent (know deeply and use effectively).
- Become familiar with the overall structure and terminology of the formula sheet.
- Identify the key connecting themes. Understand how various aspects of the sheet are related.
- Understand the ideas conceptually. The brain remembers meaning better than abstract symbols.
- Identify the technical details which will be handy to look up, when needed, but which we will not memorize.
Here are some formula sheets (aka reference sheets or cheat sheets) I like.
