Flexible Delivery that Fits Elementary and Secondary Schools Mathematics Navigator is designed to fit the particular scheduling needs of elementary and secondary schools. The elementary modules are typically delivered in 30-minute daily sessions by a teacher or paraprofessional who does not have to be a math expert. The secondary modules are often delivered during the school day in a 45-minute class by a math teacher. Both the elementary and secondary modules work during school hours and in after-school, weekend, and summer programs.
