The Course Library is where every course you can teach with Intertwined lives. You can browse it by subject, search it by topic, open any course to read it the way your students will, and add a course to one or several of your classes in one step. Browsing never changes anything for your students; only adding a course does.
Available on: every plan, including Free.
Opening the Library
In the left sidebar, open the Library group.
Click Courses. You can also go straight to app.intertwinedfinance.com/courses.
The page is titled Courses, and the line under it tells you how many courses you can open and add to a class.
Good to know: there's a second way into the same catalog. Inside a class, Coursework > Assigned Courses > Add Course opens a picker with the same courses, set up for adding to that one class. See Adding a course to your classroom.
How the page is laid out
From top to bottom, you'll find:
A search box ("Search courses or topics, like inflation"). It looks at course names, descriptions, subjects and every unit name, so a topic search finds the courses that teach it, not only the ones with that word in the title. While you search, the page shows how many courses match, for example "3 of 12 match".
Subject buttons, such as Personal finance, Economics, Business and Finance & data, each with a count. Click one to jump to that shelf.
In your classes: a strip of the courses already in at least one of your classes, with the class names in green. Click one to open the course. This strip hides while you search.
Shelves, one per subject. Under each shelf name, a short line tells you what kind of courses are on it, for example "OpenStax textbooks · Intro college".
Retired editions, folded away at the bottom (more on these below).
The Personal finance shelf and the recommended course
Personal Finance Core Foundations (3e) leads its shelf as a wide card with a Recommended label. It's our current personal finance course and the one we recommend starting with. Its card shows:
A one-line summary and the course's details (source, number of units, level).
A What's inside list of every unit, so you can see the scope at a glance.
A note that Twine Town comes with it: each section a student finishes counts as a work shift in their town. See Twine Town: teacher guide.
Reading a course card
Every other course gets a card with the same parts:
The book cover. Click it to open the course.
The name and a details line, such as "OpenStax textbook · 20 units · CC BY-NC-SA 4.0". The last part is the book's open license (Intertwined's own courses don't have one).
A one-line description of what the course covers.
Which of your classes have it. A green check with "In Period 1 and Period 3" means it's already assigned there. "Not in a class yet" means none of your classes have it.
Two buttons: Open takes you to the course page, and Add to a class lets you add it to any of your classes.
How the three economics books fit together
At the top of the Economics shelf, a short explainer shows that Principles of Economics 3e is the full-year book, and that Principles of Microeconomics 3e and Principles of Macroeconomics 3e are its two halves, one semester each. The halves share their opening chapters and the chapters on trade. Pick the full book for a year, or the half you teach for a semester. Choosing the right course for your class goes deeper on this.
Retired editions
Older editions of our courses sit in a dashed box at the bottom labeled with a count, such as "3 retired editions". Click Show to see them. These keep working in classes that already have them, but they won't get fixes or new content, so they can't be added to a class. If one of your classes still uses one, it's labeled with that class's name, and you can still Open it.
Adding a course from the Library
On the course's card, click Add to a class.
In the Add to which classes? panel, tick each class that should get the course. Classes that already have it are ticked, grayed out and marked Has it.
Click the button at the bottom, which reads Add to 1 class or Add to 2 classes (and so on).
A message confirms which classes got the course. Students in those classes see it in their course list right away. The full walkthrough, including what students see, is in Adding a course to your classroom.
Licenses and covers
At the very bottom of the page, a note explains that the OpenStax textbooks are shared under Creative Commons licenses (CC BY 4.0 or CC BY-NC-SA 4.0, shown on each card), and that the OpenStax book covers are used with permission of Rice University. More in OpenStax textbooks in Intertwined.
Tips
Search by the topic you're about to teach ("credit score", "supply and demand", "inflation") rather than by course name. Because unit names are searched too, this is the quickest way to find where a topic lives.
Use Open to read a few lessons before you add anything. Opening a course is private to you and records nothing.
Planning several sections of the same course? Add it to all of them at once from the Library instead of class by class.
The In your classes strip is a quick way to get back into a course you're teaching without going through a classroom.
Common questions
Can my students see the Library?
No. Students only see the courses on their own classes, on their My Courses page. Nothing in the Library reaches them until you add it to a class.
Why can't I add a retired edition?
Retired editions no longer get fixes or new content, so new classes can't start on them. Classes that already have one keep it, and their students' work is unaffected. If you're choosing for a new class, start with Personal Finance Core Foundations (3e).
Are the OpenStax textbooks included in my plan?
Yes. The OpenStax textbooks in the Library can be added to a class on every plan, including Free.
Does the Library include classes I co-teach?
Yes. The class names on each card and the list in Add to which classes? include classes you co-teach as well as your own, in the same order as your Classrooms page. A co-teacher can add courses to a shared class too.
I searched and nothing came up.
You'll see "No course matches" with your search. Try a broader topic word, like "budgeting" instead of "50/30/20 budget", or clear the box to see every shelf again.
