Any adult wanting to learn the material (whether you are a director/tutor/ or parent) should complete the Boot Camp. I gear the videos and discussions towards adults who are helping guide their students.
For the students, we offer three levels. The original Math Explorers - Middle School, was created for Ch A and Ch B students working in Complex and Monomial booklets. We've had many families with younger children who found the videos to be useful as well. Even if you have a Ch A student who is working through a lower level with their math lessons (like Reals or Rationals), you should still enroll them in the Math Explorers - Middle School so they are receiving the math knowledge consistent with their level. You can always tailor the work and complete fewer pages per day (it's common to have 2 pages instead of 4), or complete a lower level for the work at home.
Math Explorers - Binomials is meant to help students through freshmen algebra math concepts and calculations. The level of calculations increased and therefore each of the high school levels will need their own course to teach the math concepts.
Math Explorers - Elementary is geared around the Fraction level of material but can be suitable for the mid-elementary level. This is a nice option for students who are still building foundational math knowledge and are not ready for pre-algebra concepts.
