Using a Word Bank to Foster Vocab Usage

The language of mathematics is important. With CCSS students are going to be expected to communicate precisely and accurately (Mathematical Practice 6: Attend to Precision). In addition, students are going to be expected to explore math concepts and use math vocabulary to explain  math processes (Mathematical Practice 3: Construct Viable Arguments and Critique the Reasoning of Others). Try adding a word bank to mathematical tasks to encourage the usage of specific math vocabulary. It is important that students have been explicitly taught the meanings and conceptual understandings behind the words before they are asked to use them. Repeated exposure and authentic usage can help math vocabulary to be meaningful, specific, and precise. See how the following activity was adapted using a word bank. Students are asked to use specific math vocabulary to defend their thinking. Click on the image to grab your copy.
