Annette Haines provides a comprehensive overview of concentration across the planes. She first lays the foundation for thinking about student engagement: It must be understood that concentration is found through the interest of the child, which is guided by the sensitive periods. When we understand the child's development in this way, we can offer the most likely "hooks" to catch the child's interest and create engagement. Haines offers examples of hooks at each plane. Along the way she weaves in the science of the brain to further enhance understanding of the development of the young child and to reinforce the "why" behind behavior. [This talk was presented at the NAMTA conference titled Finding the Hook: Montessori Strategies to Support Concentration, October 6-9, 2016, in Columbia, MD.]
