I use a hybrid of curricula from Montessori to traditional. I have combined these into an effective and inviting learning environment.
My preschool is center-based. Each day the children are free to choose what interests them from science, math, writing, dramatic play, or art. Although I do encourage them to try everything, each center provides a learning-rich activity for the child.
Circle time allows the children to sit together and sing songs and discuss the world around them based on a weekly theme.
