Yes, the question Who is making What to Whom and How? That is a great essential question as you mention, can be introduced to any grade level to develop their higher level of thinking on Maslow's scale....As to encourage my students to develop their comprehension skills to write, the Who, What, Why, Where, When and How questions after a reading passage...as eventually I want them to use to process automatically as they read without having to write it down. Learning this skill will help them take any comprehension test, especially the CASHEE.
