Which of the following is an example of a pre-writing activity used in Montessori classrooms?

Metal inset books are indeed a prime example of a pre-writing activity used in Montessori classrooms. These tools consist of different shaped metal insets and a frame that allows children to practice their pencil control and develop fine motor skills. By tracing around the insets, children enhance their grip and control of writing tools, laying a solid foundation for future handwriting. This focus on motor skills aligns perfectly with the Montessori philosophy, which emphasizes hands-on learning and the development of tactile skills necessary for more complex writing tasks later.

In contrast, the other options are not primarily focused on the physical development of writing skills. Creative writing exercises demand higher-level thinking and composition skills that typically come after children have gained some proficiency in writing mechanics. Group storytelling can be a valuable exercise for creative thinking and oral language development, but it does not specifically address the physical act of writing. Reading comprehension worksheets focus on understanding text rather than developing pre-writing skills. Thus, metal inset books stand out as an appropriate choice for pre-writing activity within the Montessori framework.
