Learning Philosophy
Polliwog Preschool is play-based and student-driven with a combination of activity choices, discovery explorations and specific activities that relate to the current theme. Activities are designed to address each child’s developmental needs while encouraging curiosity, fostering love of the natural world, and developing the whole child. Polliwog Preschool uses nature as the guiding theme to frame our core curriculum areas of science, art, music, math, language and literacy. For example, when studying insects, children act out the life cycle of a dragonfly and fly through the forest for creative movement. Investigative, quantitative and analytical skills are developed as we compare, count and study terrestrial and aquatic insects. Teachers model careful treatment of nature and the creatures we examine are released back into their natural habitat. When out of the woods and back in the classroom, we extend our learning and creativity in various ways, such as painting an insect at the art station or creating an insect story as a language art activity.
