When I was studying to be a teacher, one of the classes I had to take was Literacy in Secondary Education. Since the word
*literacy* is associated to reading and writing by most, it would strike many as a surprise that Math teachers have to take courses on literacy. However, literacy is the most practical and crucial aspect of ANY academic discipline, simply because it involves the ability to read and write in said subject. For mathematics, it could not be anymore important. If you cannot understand the words that I am using, then it is almost as if we were communicating to each other in different languages.

So whatever subject you are studying, I suggest you learn its vocabulary.

As the helpful tutor that I am, I will share a list of vocabulary terms that was distributed in my literacy class to all of you so that you can check your own vocabulary. Keep in mind that this is considered to be the Mathematics vocab that one should know by the time they finish high school. If you don't know them all, that is fine (honestly most of us forget terms we do not use consistently). Keep in mind that the goal is to know as much of the list as possible.
**Parents!!! This is also a good way to see what your children have been learning in school!!!**
