writing
Step Up to Writing is an excellent program to get kids into the organization of writing. (it's heavy on organization and ideas and light on the voice/style component that 6 traits covers.)
Step Up does have a primary component, though.
does your district have a writing assessment that your grade must do? my advice is get more involved with it-- in our district, the 6th grade must write an expository essay in march (ack! this coming wednesday!!) and 6th grade teachers from around the district score it with a 1-5 scoring rubric. i was asked several years ago to help the district make a "Pencil Box" to help 6th grade teachers prep for this assessment. this involved having our students write "fake" DWA's (direct writing assessments)--they have 90 minutes to create a "final" essay. we then used our scoring rubric (after fine-tuning it) to score those essays and create samples of all different scores--so teachers and students know what a 3 looks like, a 5--an NS (not scorable) due to illegibility (?), format other than essay, and not on prompt.
anyway, every year since then, i have attended the scoring session for these DWA's. (we aren't allowed to score our own schools, or any students' that we know.) i feel this has made me a much better writing teacher because i know what they need to be proficient writers--also, i lost that dread of scoring a class of essays--i just use the scoring rubric to give a holistic grade rather than nitpicking every thing. (i teach my class the scoring rubric, and we occasionally score sample essays--and i have them tell me what they need to add/fix in their writing to earn a higher score.)
hope that helps!
