Vocabulary comprehension is crucial for students learning mathematics. This template can be used to build vocabulary skills as the students are asked to define the the vocabulary words you provide and then prove that they understand them. Great way for students to create their own "math dictionary" for the terms that you may be using in a particular unit. My students add these to their notebooks when they are completed for a cumulative list of math vocabulary. Appropriate for many grade levels as you provide the words that they are learning about.
