Sometimes you have a sequence of lessons which don't fit any regular pattern.
Our Jacob's Algebra textbook is divided into chapters, each of which are divided into a different number of lessons. Chapter 1 has 9 lessons, chapter 2 has 6 lessons, chapter 3 has 7 lessons, chapter 4 has 5 lessons, chapter 5 has 8 lessons, and so on.
Of course, you could use nested sequences to express two different incrementing ranges. But in this case, its not quite right. The second (inner) sequence has a different range, depending on the first (outer) value, and you'd have to do a great deal of editing and bumping after creation.
You could also create the lessons one chapter at a time. That would work, but is not the user experience I am looking for.
Enumerated Sequences
Enumerated sequences express explicitly the start and end values to use in multiple ranges. They are designed for the case above, where there are different values in each range.
You can express an enumeration by following your range with a comma ',' followed by another range, (which can be followed by another comma, and another range...)
The result is the series that we want, all in one swift click:
Chapter 1 Lesson 1
Chapter 1 Lesson 2
Chapter 1 Lesson 3
Chapter 1 Lesson 4
Chapter 1 Lesson 5
Chapter 1 Lesson 6
Chapter 1 Lesson 7
Chapter 1 Lesson 8
Chapter 1 Lesson 9
Chapter 2 Lesson 1
Chapter 2 Lesson 2
Chapter 2 Lesson 3
Chapter 2 Lesson 4
Chapter 2 Lesson 5
Chapter 2 Lesson 6
Chapter 3 Lesson 1
Chapter 3 Lesson 2
Chapter 3 Lesson 3
Chapter 3 Lesson 4
Chapter 3 Lesson 5
Chapter 3 Lesson 6
Chapter 3 Lesson 7
Chapter 4 Lesson 1
Chapter 4 Lesson 2
Chapter 4 Lesson 3
Chapter 4 Lesson 4
Chapter 4 Lesson 5
Chapter 5 Lesson 1
Chapter 5 Lesson 2
Chapter 5 Lesson 3
Chapter 5 Lesson 4
Chapter 5 Lesson 5
Chapter 5 Lesson 6
Chapter 5 Lesson 7
Chapter 5 Lesson 8
Note that if I did not provide enough lesson enumerations for all my chapters, Scholaric would repeat the last one to fill out the remaining chapters.
Happy Planning
