Recently the Washington Post ran an article featuring a high school sponsored poker club.  The article appeared to support the idea that poker clubs were a legitimate way to help students learn mathematical concepts. Although using the structure of poker to create a lesson in probability is a valid and effective technique; creating a club that is dedicated to playing poker and then claiming that it is academically suitable demonstrates extremely poor judgment on the part of the adults involved.     

Teaching the wrong things

When asked about the group, the principal of the school gave his support to the concept.  He told the Post:   

“We know the kids could play outside of school, but when they're here, we have the opportunity to show them how to play responsibly and to show them how the game relates to their education.”

While the rules of poker are based in large part on the laws of probability, teaching students how to play the game has far more to do with gambling than mathematics.  It was clear that the “math first” message was becoming obscured when posters advertising the club featuring pictures of poker playing dogs smoking cigarettes began to appear in the building.  The principal ordered them torn down.   This gesture eliminated the pictures but not the inherent problem.  

A very good teaching tool

When I taught probability to my pre-calculus students I regularly used poker hands as a portion of my lessons.  The standard deck of playing cards with its 13 different values, four suits and two colors presents unlimited possibilities for constructing problems and illustrations.  One of the classroom activities consisted of dividing the students into small groups to determine the probability of seven specific five-card poker hands.  After mathematically computing their answers, the results would be compared and the method for computing the correct probabilities was demonstrated.  The concluding activity was to rank the value of the hands correlated to the diminishing probability of their occurrence.  It was then determined that this student-created listing was exactly the same as the actual rules of the game.Instead of pulling out the poker chips after this worksheet was completed, the next step was to expand the understanding of the probability involved.  For example, it had been previously determined that the likelihood of having five cards and no matches was 50.7%; the chance that there would be one match was 42.3%.  It was now time to turn the process upside down.  If a person was given fourteen cards what were the chances of no matches?  The answer, of course, is zero since there are only thirteen different values. The follow up problem was how many cards must be dealt in order for it to be more likely to have a pair than to have no matches?”  (The answer is seven.  Variations of this question were given on the chapter test.)

While there were lengthy conversations about playing cards in my classes no deck was ever in the room.   We did not talk about any strategies for playing these games and most certainly would not encourage anyone to do so. The major point of emphasis was the purity of the mathematics involved. Because of their precision, these numbers have withstood the test of time in a game that has centuries of history. 

Sending the wrong message

Poker clubs designed with the alleged intent of teaching mathematics are found at colleges around the country.  The idea began at Harvard Law School.  There are, however, vast differences between the reasoning abilities of graduate students and those of high school students.  The high school math teacher who hosts the aforementioned club in his classroom speaks to the age difference, “The older kids realize that it's about odds and probability," he says, "the younger ones just want to win.”

High stakes gambling on poker has been glamorized on television and on the Internet.  Having teenagers play this game of chance and giving them any indication that they are becoming mathematically equipped to control outcomes is not only incorrect but potentially dangerous. 

Should educators be concerned about youth gambling?

The following are some conclusions from a study of 1000 randomly selected adolescents 13-17 years old by the Oregon Gambling Addiction Treatment Foundation.   (Carlson & Moore, 1998)

• Seventy-five percent of teens in the study reported having gambled.
• One in ten teens was an at-risk gambler.
• Rates of problem gambling among youth were 2 to 4 times higher than the rates for adult gambling.
• Youth can hide gambling problems well.  There are no outward, physical signs.

The article in the Washington Post quoted one seventeen-year-old who had a large pile of chips in front of him as saying, “I don't know whether math class is helping me with poker, or whether poker is helping me with math.”  A very good question that I am not sure the adults at his school can answer.
