Save the paper to reuse at the end of the unit. Also save the list of facts they come up with. As they share the facts and words, don't correct them. They will have a chance to decide for themselves which of their facts were right later in the unit. Locate Hawaii on the map.
Most maps show it in a separate box with Alaska, so they probably have no clear idea.
Find out how far it is from Hawaii to your state. Visit the library to find out facts about Hawaii and to research the history. Try creating a treasure hunt for information or create committees to research various aspects of the history, or the answers to the questions in your first survey. Have the children record where they find each piece of information. When you gather again, ask the children if they now know the answer to the questions you asked at the beginning of the lesson.
