Here are some printable unit circle diagrams. One has all special angles and coordinates labeled on it in degrees and radians; one has blank spaces for all of the labels, and the third is also blank but without the spaces for radian angle measures. The first quadrant also includes the calculation for each coordinate pair, so you can discuss the pattern and how understanding the pattern removes the need for memorization of this entire page of data. The files are zipped PDFs.

In this lab, students graph yearly sunspot data and make predictions about the future of the sunspot cycle. Additionally, there is currently an interactive here ( https://www.pbs.org/wgbh/nova/labs/lab/sun/research) where students can count sunspots and compare their numbers to the actual data. If you like this, PLEASE rate it (favorably?) and consider purchasing some of my other work.

This is a collection of common geometry formulas/equations that can be printed and/or posted for student reference, possibly given for use on a quiz, etc. This is the original MS Word document, so feel free to add or remove equations as necessary.

This printout of some NASA news article headings gives teachers the chance to discuss the crash of the Mars Climate Orbiter, which happened because one contracted company built part of the computer to think in metric units and another built a different part to think in imperial units. That's $193 million wasted because people didn't carefully label their units! The back of the printout has the SI unit prefixes, so this can be an introduction to them, and how metric conversion is so much simpler
