My IB Math SL (Math Methods) students generally find the formula for calculating an arc length pretty straightforward, but they need review with the areas of sectors and segments, and they need practice converting degrees to radians in the context of a problem.
I use this worksheet primarily as an in-class cooperative learning experience for my students. It includes spiral review topics as well.
The preview file is a pdf, so you can see exactly what's in it; the product file is a word document, which you may edit for your students.
