We cover these during grammar and writing instruction. It is listed in the TOC of this SCM book. I don’t have the book, but looked at the sample. CM way covers it through grammar, dictation, writing, and speaking (according to SCM resource.)

Our favorite resources for parts of speech have been Emma Serl’s Primary Language Lessons (and her Intermediate LL,) Queen’s Language Lessons, and as part of our writing assignments. Our older four children have all used IEW. It teaches parts of speech while teaching writing. It’s not a favorite resource for strict CMer’s, but has served us well. Our youngest may/may not use IEW as I’ve taught it for so long that discussing these things is easy without a curriculum.
You might check the Free Curriculum Guide for more suggestions. You’re probably looking at 4th grade, or older for this type of instruction.
