Thinkers Book List

Many books in the Portals curriculum can be found in digital libraries such as Kindle Unlimited, Audible, etc... If you already have a subscription to these resources, we recommend that you use them to reduce the cost of your materials. You can save up to $100 per year by using a combination of digital and print resources. Use the list below to see which books you can access with a subscription to a digital library.

Many books can be purchased second hand either online or at thrift stores. Joining online homeschool groups can be another great way to find used curriculum resources such as Math and Science textbooks. Buying used books can save you nearly 50% of the cost of all your materials for each student. Portals has created a book list on Amazon to help you easily shop for the titles that you will need. Not all of the texts can be found on Amazon, so be sure to use the full list to check off each book as you shop.
