Developmental milestones and brain development stages

Review the Language Acquisition in Early Childhood Education interactive game, which focuses on language developmental stages and cognitive processes.  Write three questions you can ask your classmates that would help to evaluate their knowledge of the developmental milestones and brain development stages, and how they influence on language development and acquisition.  These questions should be focused on the main concepts in Chapters 5 and 6.  You can see several examples of types of questions in the interactive Jeopardy game.  The solutions to your questions should be able to be located within Chapters 5 or 6 in the course textbook.  Post your three questions, but do not include the solutions to these in your original post.
