Students often struggle with the relationship between mathematical graphs and the data they represent. To truly understand types of evolutionary selection, students need to be proficient with several different skills in math, science, and literacy contexts. With math, students must be able to identify variables, design appropriate graphs based on those variables, and convert data to graphical format. With science, students must be able to relate identified variables to scientific classifications and interpret those classifications based on evaluation of the scenarios presented. With literacy, students must be able to comprehend, dissect, and interpret a given passage. This presentation provides a multifaceted approach to teaching about types of evolutionary selection by making and using graph modeling manipulatives. Though the examples provided in this presentation are primarily focused for biology teachers, anyone who teaches students to interpret graph data could find the graphing manipulatives to be a useful tool as well.
