I don't think that there is one typical school today. In fact, I think that the disparity between the proficient schools and the deficient schools are sadly greater than ever. I particularly hear horror stories of poor schools in the deep south.
Having said that, I do think that there are some general trends over the last few decades. I even see differences between when my oldest attended elementary versus my two younger ones today. In general, there is only one recess and it is shorter as well as lunch period being shorter. The writing requirements have exploded. My current 5th graders were writing short paragraph assignments in kindergarten. Because reading/language arts is now all about the writing product, the students' varying reading levels are far less relevant than it used to be. The science and social studies curriculum start earlier as well (K versus 2nd/3rd grade) There is de-emphasis on handwriting (both print and cursive). Students are expected to pick up keyboarding indepedently, which many do just by virtual of early/frequent access to computers.
