Multigrade teaching involves one teacher instructing multiple grade levels simultaneously. It is common in small schools with fewer teachers than grade levels. Some factors contributing to multigrade teaching are cultural, socioeconomic, and related to small class sizes. Benefits include a richer learning environment through interaction between age groups and greater community involvement. However, multigrade teaching also presents challenges like increased planning demands, potential stakeholder reservations, and lack of specialized resources. Support for multigrade teachers can come through professional development, community engagement, and ensuring adequate classroom facilities and materials.
