A pressing engagement
Work through Section 1.5 of the Calculator Book. As you do so, bear in mind what you decided about the notes you made for the earlier sections—will you annotate the text itself in the margin, or do you need fuller, separate notes?
In Section 1.5 you are asked to complete four exercises. Do you need to write down the answers? If so, where and in how much detail? At what point should you check your answers with those at the back of the Calculator Book? When you have completed the section, glance back over the text and your notes, asking yourself what calculator skills and mathematical ideas were covered.
Some students like to see notes in the original context and so choose to annotate the text. Others like to make notes on cards so that they can be easily referenced—there are many alternatives. You need to decide on a method that will work well for you.
If you feel that the question requires a written answer then do not throw your solution away, but keep it for reference later. Remember that most of this writing will be seen only by you, so do not waste too much precious time on presentation.
When you have completed the section and glanced back to see what calculator skills and mathematical ideas were covered, you may like to compare the list of points in the comment to Activity 13(a) and (b), above with your points.
This section of the course involves quite a lot of work from the Calculator Book and you may well not be able to complete it all in one study session. This may be a good point at which to assess how much time you have spent so far and how much work lies ahead. If you have not had a break since starting Section 2, why not take one now before you press on with the calculator?
