My students and I completed two years of RightStart, and definitely enjoyed it. While it’s not for everyone, it has helped my “big picture” thinkers grasp math and geometric concepts in a new and engaging way. While there isn’t any advanced lesson planning required for you, as the teacher, you will spend a part of each day going over the lesson with your students. Definitely not a “hands-off” curriculum, but the teacher materials are very helpful and thorough. The only negative I can see with RightStart is that it ends at level G, which my middle schoolers have just aged out of. Great for both visual and kinesthetic learners.
