"Aluminum for Defense": Rationing at Home during World War II
The productive capacity of the United States during World War II surpassed all expectations. To boost that production and maintain supply levels for troops abroad, Americans at home were asked to conserve materials and to accept ration coupons or stamps that limited the purchase of certain products. Gasoline, rubber, sugar, butter, and some kinds of cloth were among the many items rationed. American responses to rationing varied from cheerful compliance to resigned grumbling to instances of blac

Developing Questions for Gallery Walk to Engage Higher Order Thinking
This site from SERC's Starting Point explains best practices for developing Gallery Walk questions which involves preparing questions based on a lecture's central concept, issue, or debate. A variety of questions can be used but the technique seems to work best with higher order questions relating to analysis, evaluation, and synthesis; using Bloom's Hierarchy provides a guide for wording questions at various levels of abstraction. Examples of various types of questions including comprehension,
