I was hoping I would get to use this interactive notebook page idea next year. I'm a little sad that I won't! I was secretly hoping to teach pre-cal next year...not sure why... I found this small unit circle from Jean Adams on TpT. It's a free download. I like that it's small enough to fit in the notebook and still has room to label all of the important information. I also drew a little coordinate grid to help students remember where the x and y values are positive and negative. Sometimes it's nice to have a quick reference.
