This is a very complicated lesson. If you are not very good at mathematics, you might find it too difficult. 
If you teach introduction to STEM lessons, it is a good class to expose them to Math words in English.

Sia sings a song called Academia which has many words about math. I let them listen to the song and then we pick out the math words and I explain each of the words. The PPT is synced to the song. If you advance the slide form Sia's photo at the right time, the PPT should automatically advance along with the song.

This is a two part lesson. If the class is fast and I have extra time, I show them some examples of Math word problems from the SAT exam.
