Rational Football League

Grades 6-8, 30-60min

In the Rational Football League, students recruit a fantasy team of football players based on randomly generated statistics presented as ratios. To understand which player to draft for each position, students leverage ratio and proportional reasoning to compare the three options, ultimately deciding which stat they deem more important. Once their team is complete, students compete in the RFL Championships, putting their six selections to the test to determine if they’d made the best choices or if their team would falter.

This activity assumes your students have already been taught how to compare ratios and proportions. It is a practice tool, not a teach-for-the-first-time tool.

Suggested lesson breakdown

This activity can work entirely hands off – the web app includes all necessary instructions to get students comfortable with drafting football players using ratios and proportions. You can also work together as a class through selecting a mascot, as every student will see the same options for that character alone, and the selection does not affect gameplay during the RFL Championship.
