I took school assemblies for very many years and never lead a prayer or sang a Christian hymn but they were all mainly Christian in character 
We had time to think about moral dilemmas silently and sang songs of friendship and wonder!
We all wanted to be kind to strangers, be good and honest people, be friendly, share , use our talents, fight the wrong doer so good prevailed, help those who were hungry, needed help etc etc. You do not have to have a religious faith to want or promote those ideals.
