A summer session, math methods course for elementary teachers incorporates 30 hours of instruction that emphasizes (1) developmentally appropriate instructional strategies, (2) hierarchical levels of increasingly abstract manipulatives, (3) ongoing assessment of student learning, (4) integrated thematic instructional modules, (5) team planning and teaching, and (6) web- and server-based math software. The course culminates in a math camp for rising first through sixth grade students who come to the university campus. The student part of math camp is a week long, full day math and robotics camp, with the math portion delivered each morning by master's level teachers enrolled in the graduate course. The integration of pedagogical components with supervised teaching comprises a type of "guided constructivism" not found in other graduate classes in the master's program.
