Title: Wildlife MathEnhancing mathematics in the career/technical classroom and providing relevance in the mathematics classroom
Description:
This integrated lesson is the result of collaboration between Chip Blanton, a wildlife management teacher, and Greg Pendergrass, a math teacher (Ft. Payne High School).
Learning to manage wildlife requires an understanding of planting food plots, creating areas for cover, and providing water. Students learn to use the math skills required to calculate the number acres and the cost of fertilizer and seed needed in food plots and sanctuaries. Given a certain amount of land students decide what part of that land they are to plant and maintain for deer, quail, turkey, rabbit and forestation.
Standard(s): [AFN] J19 (912) 5: Compare habitat needs of selected fish and wildlife species native to Alabama. [MA2013] (7) 11: Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale. [7G1] [MA2013] ALC (912) 11: Use ratios of perimeters, areas, and volumes of similar figures to solve applied problems. (Alabama)
