Angles
Last we focused on complementary, supplementary , vertical angles , etc. The students were having a hard time remembering the word "vertical". I told them that it is the one that is opposite of the angle you are looking for and it always forms a "V", either a wide "v" or a small "v". Also the kids came up with changing the "c" in complementary to a 9 and adding a 0 to remember that complementary is associated with 90 degrees. And for supplementary angles change the s to a 8 and add the 1 and 0 to associate supplementary with 180 degrees.

I have told my students that the "c" in complimentary is 90 degrees and if they put a backwards "c" underneath, but touching, a normal "c" they can create an "s". Two c's are the same as 90 + 90 so supplementary is 180 degrees.
