![When Marcus Ninth Grade Campus teacher Matthew Schwolert brings a rod and reel to class, his algebra students want to know if they are going fishing that day. Instead of taking them fishing, though, Schwolert relies on his fishing gear to teach them algebra.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2266.png)

![âI have been toying around with the idea for a few years,â said Schwolert, a B.A.S.S. Life Member and a former Flower Mound Bass Club member.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2369.jpg)
![âI have used the concept of fishing reels when I talk about slope and rate of change in algebra class, but I havenât taken it to the level that I have this year.â](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2371-scaled.jpg)

![Schwolert has also let his class watch Bassmaster LIVE during an Elite Series event, which he considered âa great opportunityâ to connect his students with their lessons on slope and rate of change with how the pros apply different reel speeds for their various techniques.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2709.jpg)

![âSlope and rate of change is a little abstract until you can put something in their hands that they can get the idea of it.â](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2737-scaled.jpg)
![Schwolert uses baitcast reels to illustrate slope (the measurement of the steepness of a straight line) and rate of change (the slope of a line) to his class of 30 students.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2738-scaled.jpg)
![âThe fishing reel is related to slope and rate of change by the concept of the reel speed,â Schwolert said.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_27402028129-scaled.jpg)
![âSo if I turn the handle one time then the spool turns four, five or eight times (gear ratio). So my students use the relationship in reel handle and spool turns to make that the slope.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2741-scaled.jpg)
![Students build their own presentations tying fishing into their explanations of algebraic concepts.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2743-scaled.jpg)
![âThe kids then graph that speed of one reel with a certain gear ratio and graph another one with a higher gear ratio,â Schwolert continued. They also build other graphs, such as this one, relating to a boat's motor.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2745-scaled.jpg)
![âThat lets them understand what slope and the steepness of the line are.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2751-scaled.jpg)

![âI have been fishing with my dad for a very long time, but I never knew algebra could be tied in to it,â said another student. âIt was a super fun way to learn how algebra is involved in fishing.â](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2760-scaled.jpg)
![âThe project has been great,â Schwolert said. âIt has given me something to use the entire semester as a reference point.](http://www.bassmaster.com/wp-content/uploads/2015/06/IMG_2787-scaled.jpg)
