Question about grade level target

Hey guys, did we say we are doing third grade? Because I was thinking that if we were, the whole skype thing seems appropriate for that level, but with weather itself is more of 1st grade(weather conditions) &2nd grade(water cycle/cloud types) GLCE's. *I'm not going to set my things at 3rd grade until I hear from you guys; I'll work at 1st/2nd.
