In many cases, we use several activities in a carefully controlled sequences, to help students see how information ties together. This is a major task for beginning upper-division learners.

• Ring Sequence Use a sequence of activities with similar geometries to help students learn how to solve a hard activity by breaking it up into several steps.
• Plane Wave Sequence: Use a sequence of activities to help students understand what is planar about plane waves.
• Representations of Fields Use a sequence of activities to develop students' geometrical understanding of electrostatic potentials and electric fields.
• Gauss's and Ampère's Laws: Use a sequence of activities to help students understand how to use the integral form of Gauss's and Ampère's laws to find electric and magnetic fields in situations with high symmetry. These activities have a special emphasis on helping students make clean, coherent symmetry arguments.
• The differential version of Maxwell's equations: Use a sequence of activities to help students understand the differential versions of Maxwell's equations. Included are activities that address the geometric interpretations of flux, divergence, and curl and also derivations of the Divergence theorem, Stokes' theorem, and using these theorems to derive the differential versions of Maxwell's equations from the integral versions.
• Boundary conditions Use a sequence of activities to help students derive the boundary conditions for electromagnetic fields across charged surfaces or surface currents.

• Effective Potentials

• Using a sequence of activities, some computational, to help students understand how to visualize electrostatic potentials. More potentials?
