Glossary Bingo Each student receives a copy of the glossary terms and a single glossary bingo card (each card contains random 9lossary terms). As a class, read through the glossary terms. Students are then given 5 minutes to revise the terms and definitions. The teacher reads out definitions in a random order. When the student hears a definition of a word on their bingo card they highlight it. When students have a row of three terms they call out “Bingo”. An example of a bingo card can be seen below, but the downloadable file below contains multiple variations.
