What We Do

At The Happy Children’s Montessori our goal is to provide a program which helps each child grow academically, socially and spiritually. Montessori is a hands-on, individualized program in which children are encouraged to learn at their own pace in the areas which interest them most.  In doing so, each child soars in his or her learning journey.

The areas of the classroom include art expression, practical life (i.e., handwashing, pouring, polishing, sewing, dressing frames, hammering and more), sensorial (materials that help them to differentiate between different dimensions, colors, sounds, smells and touch), math, language, science, geography, botany, zoology, history, French and music (our song selections are from standard children's songs, Bible songs for children and French songs).

Self-directedness, concentration and focusing skills, a strong sense of responsibility, respect for oneself, one's environment and the people in one's environment and an ability to make choices are all important life skills that children learn and keep with them for the rest of their lives.

Our program encourages children to use respectful conflict resolution skills with one another. We use grace and courtesy lessons to teach manners, proper handling of materials, respect of one's classmate's work and workspace and respect of the environment. We always stress the importance of treating each other and the materials in the classroom with respect and kindness.

The Happy Children’s Montessori is a Christian based school in which Christian values are taught.  Each child learns that he or she has been beautifully and wonderfully made and is loved deeply by God. Monthly, we explore a new theme, including how to be a good friend, joy, love, giving, honesty, forgiveness and gratitude. The children are presented with Bible verses which correspond with the theme of the month and helped to apply these principles to their daily lives.

After graduating from our three year program, children leave with advanced academic skills, beautiful social graces and a strong sense of self confidence. Further, each child knows the joy of learning and is ready to excel at whatever school he or she attends in the future.
