Teaching Materials
Positives
- This game provides opportunities to make connections to students' local realities, which will enrich the learning experience.
- This game does a great job of helping students see how overfishing works and almost forces the "aha" moment, especially if using the method shown in the video.
Prerequisites
- Students should understand the importance of having enough of a species to continue its population.
Differentiation & Implementation
- Before playing, teachers of younger students can have a math activity where students are asked to rank the four candies that will be used to represent the fish species. The class can then compile and graph the data, using the results to determine which candy will represent which fish.
- After playing the game, teachers can explain how climate change and ocean warming will impact ocean species, making sustainable fishing even more important.
- This module is specifically about the Gulf of Maine and the impacts of climate change on its fish species, but it may also be useful for students outside of Maine.
- Teachers can use this game to make connections to the Sustainable Development Goals, highlighting the connection between SDG 2, Zero Hunger, and SDG 14, Life Below Water.
With this fishing game, students will learn about how overfishing or a lack of regulations can contribute to or cause the collapse of a fishery. The game encourages students to think about responsible fishing and to interact with our environment, and it depicts the importance of prioritizing sustainability. Additional resources, including an article written for kids and videos, are provided and offer a good background for the game. The information presented is accurate, and this resource is recommended for teaching.
