Leave the last several pages, or more, of the math journal blank for the glossary. Depending on the amount of new terminology expected throughout the year, you may divide terms alphabetically by designating two or three letters per page. To keep it simple for students in kindergarten through second grade, list glossary terms in the order they are learned.
Write a title at the top of the page, such as "Glossary," "Math Terms," or "Math Vocabulary." Older students can write or copy the title themselves. Add letters and dividing lines to each page if listing glossary items in alphabetical order.
Explain to students that the purpose of a glossary is to write new math terms as they are encountered. Tell students it will be a useful learning tool to revisit old vocabulary or to review all they have learned.
Introduce new vocabulary before the lesson. After the lesson, check for understanding by asking students to write the term in their glossaries. Ask students to write the word, a definition using their own words, and a picture. Help younger students by doing the first few words as a class or by providing individual assistance.
Continue adding new words to the glossary as they appear in future math lessons.
