How good is Highgate? What is their curriculum like? My child is attending a preschool playgroup, and they charge $250 for an hour during their summer sessions. (each session is 2 hours)To be honest, the classes are absolutely excellent, the teacher was a montessouri (woodland) teacher, and I have enjoyed every class with him, from morning aerobics, to circle time, to cultural lesson, to arts and craft, to dramatic play ....I started off with 2 days a week, then added a 3rd day, the a 4th day now.. I switched my son out from his other playgroups to attend this new playgroup but it is costing me an arm and leg. thinking of other good options. any suggestions?
