Beetle races make algebra move

Posted on Updated on

In eighth grade algebra, students began a unit on linear functions by looking at things moving at a constant speed. In this lesson, the thing that is moving is a darkling beetle! Each group got a beetle they let run on a piece of paper, recording its path and noting it’s position in five-second intervals.

Students will measure this path, build a data table, make a graph, and — ultimately! — figure out which group had the fastest beetle!
