Five variations on bingo
There are some easy variations if you want to get away from the standard "call out numbers" version. By the way, you can buy ready-made bingo cards with numbers 1-90 - it's a good to have a load of them in the cupboard - or students can just write down, say, 10 numbers in a range you give them. One advantage of having "official" cards is that you can do lines as well as the "full house".
1. Mental arithmetic bingo
With this one, instead of reading out a number, you give classes a simple mental arithmetic sum to solve which leads to the number which may be on their card. You need to teach them simple terms like plus, moins, multiplié par and divisé par. The advantage of this variation is that it provides more mental challenge. The downside is that pupils don't make the immediate link between the number you read and the number written in front of them. You might also need quite a good class to do it.
2. Reverse bingo ("death bingo")
In this variation all the class stands up. You call numbers and if a number comes up which is on a child's card, they must sit down and they are out of the game. This variation goes by quite quickly and is a fun alternative, but the obvious downside is that once a pupil is "out" they have no more motivation to listen to numbers.
3. Number sequence bingo.
Instead of just reading a number, you read simple sequences of numbers and pupils have to work out what the next number would have been. You can make this as simple or as hard as you want, depending on the class. e.g. 1,2,3,4 ___ . Or 64,32,16 __. You can cater for any number easily e.g. 5,4,3,2 __. I like this version because students get to hear a lot of numbers, so you are maximising input. the minor downside is that, as in mental arithmetic bingo, pupils do not make an immediate match between the number they hear and the number of the paper.
4. Group bingo
Just break the class into small groups and get one person to act as caller. This has the advantage of allowing some students to do the calling. The downside is that students may hear poorer models of pronunciation and there is the danger of an over-noisy classroom.
5. Number in a sentence bingo
In this variation, instead of reading out a number, you read a sentence containing the number. e.g. Il y a 30 personnes dans la classe; j'ai deux frères; le numéro soixante est intéressant. This has a greater level of challenge and is an opportunity to provide input at the sentence level, allowing pupils to hear numbers in context. Some classes may find it too hard and the teacher may need to do a bit of thinking beforehand about the nature of the sentences which are feasible. This may be a version to do with classes who have been studying at least a year.
