For younger students with no background in Physics, I highly recommend the Survey course. If your child is older and wants to start a sequence similar to the courses taught in US high schools and colleges, I recommend taking full-year Mechanics in the first year and then full-year E&M in the second year.  Many of my students who start in the Survey of Physics often stay in my program for two or three years. The electives (see below) are open to any student at any level and intended to supplement the program.  The physics of sports offered on Fridays is a good starting point.
