I remember when I was teaching that I placed a lot of emphasis on the vocabulary in my math classes. The students didn’t always understand why the vocabulary was important. “Why don’t you just say top and bottom?” “Because it is the numerator and the denominator.” I actually had an administrator complain once that the words I used were “too big”. What?! I explained that I would continue to use those words, because they are the vocabulary that the students will see on state assessments.
As I tutor some of my clients, I come to realize that some teachers still do not use the proper terminology in math class. Sometimes that you other words or expressions to help students remember. This is all good. But the emphasis should be on the proper vocabulary.
So how good are you at your math vocabulary. Take the math vocabulary quiz below. Match the vocabulary word with the correct definition. Try not to peek at the answers until you’re done. 🙂
