Cross-Curricular Projects: How??

I always want to show the students how math is connected to other subjects and the real world.  Frankly, one of my big dreams for our math program is not to get more girls to calculus (but YAY! if that happens).  Rather my dream is that it starts to blow up the idea of “time” and “school day” enough that we can start to incorporate cross-curricular time in the day.  How cool would it be if instead of teaching dimensional analysis in physics and again in algebra, we taught it concurrently in the context of a bigger problem?  But how do we inch towards this?

This year I have tried two cross-curricular projects:

  1. Math (Financial Algebra) + College and Career: Ginger helped me design a unit about the realities of paying for college.  She taught the introductory lessons (on block periods) and popped in as I continued this mini unit through the following week.  The feedback was very positive and many thought that all of their junior classmates should have access to this unit too.
  2. Math (Algebra Readiness) + Religion: Adam and I got our classes together in the Innovation Center to explore examples of the Fibonacci Sequence in nature and discuss the implications.  Is this mathematical pattern proof of a common creator?  This was really fun, but the feedback that I got from my freshmen students was that it was awkward to work with a different class of students (in this case a mixed-gender class of seniors), especially for just one class period.  My personal feedback is that the lesson we designed should’ve been spread out over a week or more — it was really dense.
Moving forward I have questions:
  1. What is the most logistically efficient way to do a unit/project with another teacher/department?  Working with Ginger was easier than with Adam (no offense Adam!) simply because she did not have a classroom full of students that were expected to collaborate with mine.  I know my colleagues all have prep periods (which would eliminate the concern of having to join classes) but that’s a big ask and I’m just not there yet.
  2. Does a cross-curricular course make more sense than a cross-curricular lesson or project?  Yes, if the only concern is finding overlapping time and a similar student population.  No, because creating a new course feels like a huge barrier to cross-curricular work.  Also, if we keep increasing our course offerings do they eventually get watered down?  
  3. Anyone want to try another cross-curricular project/unit with me?
