TenSun combines responsible innovation with meaningful activities to deliver authentic student-centered design. Earth’s Contintents (pictured) is the first title in our MyWorld™ Geography Series. Lesson design is based on three-years’ work with three- to six-year-old students in Lexington Montessori School Children’s House classrooms. Exposition, recall, and reconstruction lessons allow children to self-select their level of difficulty. Students who master all three lessons will also acquire technology skills recommended by the US Department of Education for exiting kindergartners.
