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 choose 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.
