Bingo

Bingo is a game of chance played with randomly drawn numbers which players match against numbers that have been pre-printed on 2x8 matrices (3x8 in real game in Spain).

So the first thing we need is a card with those matrices and you're gonna draw it. Here are the instructions:

1. Draw a table with two rows and five columns like the following one:

Preparing the game:

1. Draw a two times five table.

2. Choose 10 numbers (natural) between 1 and 50, included.

3. Set your numbers in the cells. They must be sorted following the header (units to the first column, tens to the second one, twenties to the third, and so on).

4. Write five numbers in each row.

Let's get it started

1. The numbers will be chosen randomly. Sometimes, the teacher will do the extraction in advance.

2. The teacher will read not that number but an operation that the students will have to perform in order to get the “real” number. For example, if the chosen number is 25, the teacher will say “five squared!”.

3. The students must work out the result and check if they have the number in their card.

4. Once someone match five numbers in a row, he or she should call out “LINE!”. The student will read aloud his or her numbers and the operations. If they are correct, he or she will win a positive point. Every line will be awarded, one per turn, as long as it doesn't contain exactly the same five numbers that a previous line.

5. The one who match their 15 numbers will call out “BINGO!” and will win another positive point. The game then stops.

Notes

1. The students must pay their whole attention because if two of them match a line or a bingo at the same time, only one will win the prize: the first one to make the call.

2. In some cases, the teacher will call out the operation two or three times and then write it on the board. So you can be quicker if you pay attention to the first call.

Some examples:

• Integers.

• Percentages.

• Fractions, decimals, powers and square roots.

• Bingo de ecuaciones.

• Trigonometric ratios.
