During that month, brainstorm with students on how other cultures have contributed to humankind, i.e. the Chinese inventing paper, how did this change our lives. This can link to the next unit which is world history. Be sure that the students document their findings for assessment exam purposes. After every student has shared, have a small world party. Each student can use the items that they found about their culture to decorate their desks.
Students can then walk around the room visiting each person's desk.
Afterwards come together as a class and discuss what you saw. Show them that you have a whole world just in you classroom. Give them a list of the names of students that presented the previous week and have them write down what they learned about that student. Have them write between 2-3 things that they learned. Also, on the exam, have the students write down what each culture has contributed to humankind.
