8th Grade Math

At Corvian Community School, we strive to develop our students into independent thinkers and problem solvers. We feel strongly about the use of hands-on, inquiry-based learning, integrated activities, and differentiated instruction. Sometimes our students will be engaged in integrated units of study where mathematical skills and concepts are couched into a scientific context. In other instances, we will teach math and science separately, but often with a project-based approach. In 6th, 7th, and 8th grade we will align the curriculum and capitalize on the natural math/science connections that can occur at each level of study.
