My team and I have been teaching with a new math program for about 4 years. We love the unit on two-dimensional shapes and their attributes. However, there is sooooo much new vocabulary for our students. I created this quick and easy to use dictionary for students to keep in their math folders. After I introduce new vocabulary, students write down the word, a definition, an example, and a non-example. This student created resources is handy to refer back to and I even let the students use it during the test.
