I realize that I have not used open ended materials often. However, when I did to this I was amazed at what children did. Now that I have a better understanding of open ended I will plan on using open ended materials more often. I know that open ended materials help children with their critical thinking. I think that I have used materials like scarves and ribbons in a more open ended way. We often turn on music and just sing and dance. That is an activity the younger and older children do well together.
