I came across this site with syllabi for primary grades:
(Grades K – 5 )
The syllabi range from computers, Islamic Studies, math, literacy and communication to science.
I thought these were really nice because in addition to benchmarks, for some of the syllabi they list a content plan which lays out, by reporting periods, the topics w hich is helpful for scheduling.
The literacy and communication ones seemed especially helpful (at least for me). In addition to a reading/grammar focus, there is a writing focus which lists types of writing activities given.
