Open ended material in my program may be blocks of different types , sizes, people, animals, vehicles and buildings. The block center is well rounded for all domains. Dramatic play with a variety of costumes & props with ample time to get/be engaged to play and interact. Music and dance with an open microphone. Great opportunity for children to hear the sound of their voice. It always sound different when speaking into a mic. Reading a book with open ended question before, during and after the story. Let an older child read to a younger children. Sand play with toys (tubes, cups, wheels) outside. Miniature sand boxes that have a theme. These boxes are created to have figures & props to create a story.
