Carnation Co-op Preschool is hosting an open house event for parents and children, 10:30 a.m. to noon, Saturday, Aug. 29.

For 40 years, Carnation Co-op Preschool has been preparing the Valley’s 3, 4 and 5 year-olds for school.

“Children learn best by doing” is the school’s philosophy. Dedicated teachers and parents provide a safe and fun environment for both guided and free-time activities for 2.5 hours each school day.

Younger students attend school two days a week, once with the older students, who have school three times a week. Each class is capped at 12 students. Parents attend monthly meetings on co-op business, which also include presentations on child rearing, development and discipline.
