Functional Maths ideas?

No posts for a while as work has got predictably manic. Had a productive morning planning A level lessons ready for the two observations I have coming up. Now I'm teaching 27 hours a week I seem to be struggling to keep up with everything. The admin alone seems to fill my time and I have little time for actually thinking through the teaching and learning except on weekends. I probably have taken too much on which is my usual habit. My other hat is functional maths co-ordinator and I'm struggling to find interesting resources for this. I have a bunch of problems for them to solve but I want to create something relevant to engage them. Any ideas? I thought of something to do with alcohol consumption and when it would be safe to drive the next day but thought that could backfire on me.
