These are worth a look as they include more ideas for exponential projects and expansions like delayed exponential growth (essentially Fibonacci-like), logistics ad delayed logistics.
They will need some work to use, however, as the algebra notation will probably need to be changed to match our curriculum and I would make the spreadsheet instructions less exact so the students need to think some about how to model. I’ve only looked at one unit so the scaffolding on Excel may decrease over time.
