I teach Computer Science (in a small district) to Grades 4 through 7. I meet with students once every 4 days and uses Courses 1-4 with them as part of the curriculum. I find that in our situation, Courses 1 to 4 are a good match for grades 4 to 7 respectively. The expectation is that by the end of Grade 7, students would have complete through Stage 18 of Course 4. Our students switch to Python in Grade 8.
How long will Courses 1 to 4 be available after the implementation of Courses A to F? If for at least one year, would the puzzles in the stages be updated to similar ones in the new courses? For example, would the collector be added in appropriate places?
Also, since I have students at al levels of Courses 1 to 4, how would progress be affected if they all migrate to the A-F system? Not being sure, I am guessing that what would work for us here would be to start all new students in A-F, but have current students complete 1-4.
