TBIL Resource Library

We currently offer classroom-ready materials for Calculus and Linear Algebra. New editions are released twice annually around January (our "Early" edition) and August.

Calculus 2024 Edition

Linear Algebra 2024 Edition

We have also just released a Trial edition of materials for pre-calculus classrooms. Note that these have not yet been used in classrooms; instructors are encouraged to join the conversation at http://chat.tbil.org to join others trialing these activities in their classrooms in Fall 2024. You may wish to use this in conjunction with the Preview edition below, which is constantly changing as we make updates and fix things.
