Instructions for summarising textbook sections after you read

Part of your homework is reading the textbook. I am not expecting deep reading with full comprehension, but I do want you going through every section in its entirety at least once and try to determine what are the major themes/facts. After reading you should understand well enough to be able to tackle the (typically straightforward) online homework. I expect you to summarise each book section you read according to the following guidelines

1. The summaries should be written in the back of your notebook.
2. Write down what you think are the FIVE most important items in that section. These may be definitions, theorems, techniques, examples ... they could be anything. Make sure you copy down whatever you are writing (eg a theorem) in full .
3. Your summary should be at least half a page in your notebook. Your summary may be longer if you want and may contain more than 5 items if you want.
