This is more than the other bingo games one sees.
Each game has 50 words, in this case the periodic table.
There are 20 bingo cards.
There are 50 'bingo calling' cards.
There are 50 random PowerPoints for easy bingo calling.
Some of the bingo games have extras like a wordsearch or flashcards.
You just need to print out the PDF and get some counters, I use small ceramic tiles but you can use anything, bottle tops, beans etc..
Each game lasts about 5 minutes.
They are great for the end of a lesson.
