Breathe, Think, Do with Sesame (Free) provides a fun context to explore these strategies with your young students (PS-grade 1). The app presents five episodes including frustration about getting dressed, separating from a parent at school, and a block tower that falls down. Interactive activities guide the student to help the "monster" use diaphragmatic breathing, visualize plans, and choose a plan to solve the problem.
In addition to the above resources, the app also aligns well with use of Braidy the Storybraid and The Incredible Flexible You Program (TIFY), the five episodes being individual Abbreviated Episodes containing character, setting, kickoff event, response, plan and conclusion, and relating to the social cognitive instruction in TIFY. See also Sarah Ward and Kristen Jacobson's terrific work on executive functioning and making a "future picture" to accomplish tasks.
