Common Core Standards
Grade 5
Writing W.5.2.C
Link ideas within and across categories of information using words, phrases, and clauses (e.g., in contrast, especially).
Based on the fourth grade standard, your students should already be comfortable linking ideas within and across categories of information, but this standard adds the dreaded clause to the mix. Egad! What's more, the use of clauses to create hierarchies of information reflects an increasing sophistication expected in your students' writing skills.
