I just taught this concept to 1st graders. I introduced this topic through a book titled: Infinity and Me by Kate Hosford. This is a “notable” book for children. The word “wonder” appears in the text. I introduce this text to begin a simple research process with the students. They will “wonder” about a topic of their own choosing and ask a question about it as a component of the WCPSS eWISE research model. Raring to go!
