I have found the use of these posters very valuable for students that find it very difficult to learn the key positions on the Unit Circle. This set of posters shows a visual method that demonstrates 3 key patterns to make learning the exact ordered pairs much easier.
I have included 12 Posters for posting that include the patterns for sine, cosine, and tangent exact values. I have also included 8 black and white copies with blanks to be filled in by the students for the ordered pairs and radian measures. I usually set out the colored pencils or markers and let the students complete their copies with a color theme to help them see and memorize the patterns for the radians and ordered pairs. Or they can use a pink, turquoise, and yellow highlighter to make their poster match the one in this packet.
