Kidssundayschool
for lessons, ideas, games, etc there is kidssundayschool. you would need to know some spanish to be able to read it. some of the lessons they have in both english and spanish. Though obviously written by a native spanish speaker, I have found grammatical errors with their materials as well, but it is all understandable.
