||This qualitative case study had two purposes; the first involved exploring the effect of Montessori Practical Life presentations being taught in the home, and secondly, to examine the potential development of children's executive functioning skills. The study was conducted over three months in a multi-aged classroom with children ages three thru six years. Three parents and three children volunteered from a classroom of 15 students. One Montessori Lead Guide and one Assistant Teacher also contributed to the study. The analysis depicted a correlation between the lessons given in the home and executive functioning skills in the participating children. As themes emerged across data sources, six themes were consistent: autonomy, self-confidence in children, emotional regulation, concentration, adult confidence, and adult self-awareness. It was necessary to collect qualitative and quantitative data through adult pre- and post-interviews, classroom observations, parent and teacher monthly checklists, and weekly parent surveys to integrate the results from multiple data sources. Findings demonstrated an overall increase in all three children's executive functioning skills. Also, the self-confidence of parents also increased and self-awareness in the adults in the classroom. The study's significance demonstrated the impact of bringing Montessori Practical Life into the home and its direct impact on parents, children, and Montessori Guides in improving executive functioning in children and building positive connections between the home and classroom.
