This lesson is intended to be used along with one or more texts (a textbook or online resources will work perfectly fine). Students are provided with a set of 16 labels that they must arrange to solve various "puzzles." Each puzzle requires students to categorize and arrange what they understand about the history in different ways. With each "solution" students must write out an explanation that defends the way they have arranged the labels. The lesson sequence, labels, puzzles and handout for students to complete during the process are all included in this file.
