Integration of SEL skills into academic routines will always happen to some extent regardless of how aware of it or intentional about it the teacher is.
In order to promote horizontal alignment and deliberateness, teachers need to be familiar with the SEL benchmarks for their grade level and then intentionally plan how they can optimize academic content and routines in order to support learning in those benchmark areas.
Quick Examples:
Reading a story and discussing where the students would make different choices than a character and what the effects of those choices would have on the story.
In social studies class, highlighting the various skills (e.g., impulse control, stress management, self-discipline, teamwork, decision making, etc.) demonstrated by various historical figures.
Providing vocabulary words such as thrilled, elated, mournful, rejected, disappointed, or irate, and have students practice using those words in their writing.
