-We're excited to share with you our first edition of -Precalculus for Team-Based Inquiry Learning! These activities, which mostly -cover topics from College Algebra, are being -used in a few classrooms for the first time in Fall 2024. More -activities are being designed to be included in our 2025 editions, -with a goal of fully supporting Precalculus courses in Fall 2025. -Similarly, our exercise bank is a work-in-progress. -

-We're providing this first edition for those who are eager to try out -TBIL in their precalculus classrooms, with the understanding that this -book will likely change a lot between now and our next edition, once we've -tried it in our own classrooms! Are you interested in joining the community -using these materials, and possibly contributing back to these free and -open-source resources? Join the conversation at ; -we look forward to hearing from you, particularly if you have feedback -from your students on these activities. -
