EnTeam.Operation Cooperation brings together third grade students and their teachers and parents from four different religious schools in west St. Louis County: Al-Manara Academy (Muslim), St. Monica Catholic School, Kirk Day School (Christian) and Mirowitz. The program hopes to break down barriers by encouraging the children to play problem-solving games collaboratively. They meet at four workshops a year and enjoy snacks at “get-to-know-you” periods. The four schools take turns hosting the events. Last Thursday, Mirowitz hosted one of the workshops for their Christian and Muslim friends — about 100 third graders in all. The school lunchroom was filled with tables and pint-sized chairs for the kids’ important work.
