Vocabulary bingo gives every student a grid and a reason to listen for the word you say, or for the definition you read while they hunt the matching word. The box opens with a general school list — grammar, synonym, fraction, habitat — so the page is usable during a demo. For a real lesson, select all of that and paste your own list. Spelling words, science terms, and Malay vocabulary all work, as long as each item is on its own line and you have 24 of them with the free centre on.
Print a class in batches of 12. Hand the sheets out face down if you care about students comparing before you start. Because each card is shuffled independently, you should still look at a pair of neighbours. A list of exactly 24 words means every card contains every word, only the positions change, and bingo becomes a race of arrangement rather than of coverage. Add extra words from the chapter if you want some words absent from some cards. That is the more useful game for revision, because a student cannot simply wait for a word they know is on every sheet.
Read definitions and have students mark the word, or read the word and have them mark it. Either way, keep your own caller list and tick what you have said. This page will not track the calls. The free centre means a student starts with one square, which shortens a warm-up at the end of a period. Turn it off for a full 25-word card when you have the time and the extra word.
The print stylesheet hides these instructions. What goes to the printer is the cards. Use the browser dialog's "save as PDF" when you want to upload the set to a classroom drive. Pictures of objects, for a younger group, are a different mode on the picture page. The word generator is the same form without this starter list.
