If they find the word, they place a counter on that square. When the children hear a word called out, they are supposed to look at their Bingo card and see if they can find the word on the card (not every word is on every card). The adult takes a long pause between each word to give the children time to play the game. The adult then marks off the word from the list to help them remember which words have been called already.
For example, if the word was plate, the adult could call out: Adult: Plate. The adult reads out the word, uses it in a sentence, then reads out the word again.
The adult takes the word list and picks a word at random from the list.
