Abstract
Magic has the ability to grab the attention of adults and
children alike, whether it is a traditional trick of pulling
rabbits out of a hat or a more sophisticated mind-reading
card trick. We started a project at our school to excite
children about mathematics using card tricks. We were
pleasantly surprised to see such a positive response from
children across grades.
In the following article, we describe how we used the 27-card
trick to introduce ternary bases to students in Grade 9.
