The Course Library has one current Intertwined course, Personal Finance Core Foundations (3e), and eleven OpenStax textbooks in economics, business, finance and data science, plus a few retired editions of our older courses. This guide helps you pick: what each option is, who it suits, how to fit it to your calendar, and what comes with it.

Whatever you pick, open it first and read a section or two. See Previewing a course as your students see it.

This is our current personal finance course, marked Recommended in the Library and labeled "High school". It runs from checking and credit to taxes, investing and careers, in 15 units:

What comes with it:

You don't have to teach all 15 units. A common approach is to pick the units that match your requirement or your semester, open only those with Manage Access, and choose the same units for the certificate.

These are free, openly licensed textbooks from OpenStax at Rice University, labeled "Intro college" in the Library. They suit advanced students, dual-enrollment and elective courses, or extension reading next to 3e. Students read them chapter by chapter, including each chapter's review material. They don't include Intertwined section quizzes, Toolkit materials, certificates or Twine Town, so plan your own assessments.

They're available on every plan. More detail, including each book's license, is in OpenStax textbooks in Intertwined.

At the bottom of the Library you'll find retired editions of our older courses, such as the earlier editions of Personal Finance Core Foundations. They keep working in classes that already have them, but they won't get fixes or new content, and they can't be added to a class. A class that still uses one shows a banner on Assigned Courses, and if the class doesn't have 3e yet, a See the current edition link that opens 3e in the course picker.

If you're moving a class from a retired edition to 3e, do it at a natural break, such as a new semester or the start of a unit. The two are separate courses, so students start 3e from the beginning and their progress in the old edition stays where it was. Add 3e before you remove the old course, because a retired edition can't be added back once removed.

Simulators aren't tied to a course. You turn them on for a class separately, and which ones you can use depends on your plan. A few natural matches by topic:

Twine Town is the one experience tied to a course: it runs only with 3e. See The simulators at a glance: which one fits your lesson.

A class can have several courses. For example, you might teach 3e and give a few advanced students chapters of Principles of Finance 2e through assignments. Students see each course separately on their My Courses page, and each course keeps its own progress, so add only the ones you'll use.

Yes. The Intertwined National Standards Alignment, in the Teaching Toolkit, maps the 2021 National Standards for Personal Financial Education (Grade 12) to 3e's sections. Certificates list the standards covered by the units a student finished.

Yes. They're written for introductory college courses, so they fit advanced, dual-enrollment or elective classes best. Preview a chapter to judge the reading level for your students.

No. Every course in the Library can be added on every plan. What changes with your plan is what you get back, such as performance analytics, the Gradebook and Manage Access. See Intertwined plans explained: Free, Solo, and school licenses.

Use 3e and pick the units you need. Assign their sections, open only those units with Manage Access if your plan includes it, and set the certificate to those units so students can still earn one.

Yes. Add the new course, and remove the old one when students no longer need it. Progress doesn't carry between courses, so switch at a natural break.
