You know your maths. This short course is about the part of the CBAs that is hard to run: three weeks of investigation for a whole class, each student owning a problem or a question, judging the work on balance, and getting through SLAR.
There are four lessons of about thirty minutes. This first one covers how the maths CBAs run now, this year's date windows, both investigations at a glance, and planning the weeks back from the SLAR meeting.
Watch this presentation for a clear picture of how the maths CBAs run now, this year's date windows, and both investigations at a glance. The key planning move is fixing the SLAR meeting first, then working backwards.
Study this filled-in CBA class planner for an invented second-year class running the Mathematical Investigation. It uses week numbers, never calendar dates, because real dates depend on each school's calendar and holidays. The week labels reuse the Mathematical Investigation stages you just saw at a glance. Read each annotation. It explains why that choice protects the sequence.
Download the blank planner and, after you study the exemplar, pencil your own Week 1 to 6 labels for one class into it or into the draft in the next step: CBA class planner (Word).
Now make the first planning decisions for one of your own classes. Use week numbers or school-calendar dates, whichever you already know, and follow the layout of the planner you have just studied. You can refine this draft as you work through the later lessons.
