I made this product as a fun way for my students to practice comparing fractions. It's based off the idea of the March Madness basketball tournament, where teams compete to see which one is the greatest. However, in this activity fractions compete against each other to find out which fraction is the greatest.
I have students fill out their initial bracket prior to teaching them about comparing fractions, so much like with college basketball there are lots of opportunities for them to incorrectly pick the winners. Next I teach students several ways to compare fractions. Then I assign students one of the fraction "games" from the tournament to preside over. They are in charge of proving who the winner is of their assigned game. When all games have been played (and the winners proven) students check over their initial brackets to see how they did. Finally, they complete a new bracket now that they know how to compare fractions.
