Everyone seems to like bingo! Here are some variations that use dominoes. The
game itself is appealing, gives students practice with addition and subtraction,
and can form a good introduction to probability.
come in three sizes,
using 9, 16, and 25 dominoes respectively. They are designed for 1"x2"
dominoes. You can make your
from the given template
using construction paper or plastic foam.
I’ve played this with students as young as grade 2. That group started with the
9-domino version and progressed quickly to the bigger playing grids. We started
with addition, then tried subtraction, then went on to a game using both.
I use plastic foam for the counters for the bingo caller, one colour of counters
for addition and a different colour for subtraction. The frequency of the result
differs with the operation, and we want each domino to have the same chance
of being chosen. For example, there is only one way to get 0 via addition
(0+0) but seven ways via subtraction (6-6, 5-5, etc), so we need to have
more 0 counters when using subtraction. Trying to figure out the number of
ways to get each sum or difference is an interesting exercise for any age .
I’ve provided frequency
in case you don’t
have time to do it before you play bingo.
Players choose enough dominoes to fill in the chosen grid. The caller chooses a
number and everyone hunts for a domino on their grid that has that sum. If they
have such a domino, they remove it from the grid. Only one domino may be
removed per call! You decide what constitutes a win: a single blank row, column
or diagonal; two of them; or a completely clear grid.
Same idea, only this time players hunt for a domino with the called number as
its difference. Students sometimes ask if order matters, so this is a good time
to discuss what “difference” means. The difference between 2 and 5 is 3, no
matter what the relative positions of the 2 and 5 are.
Once the players get the idea and have practiced a bit, try combining the two
sets of counters in one bag.
