You can't go wrong with Native American Lessons. I have tons of lesson plans left over from when I was student teaching. In the elementary school I student taught at I got to teach a lot of Native American lessons. I designed a lesson plan I was afraid would be too hard, but the kids loved it. I called it the Native American Motif paintings. They were to think about all the things they had learned about native Americans and pick a theme such as symbols (language) , hunting, their homes, some of their beliefs, things of that nature. I had given them a grading rubric that told them what all their paintings HAD to include and then let them choose their color schemes and have their painting Motif okayed by the teacher. This especially helps if the student is having difficulty with the idea of a theme or if they have picked something way too hard for them. Students who have disabilities may need a bit of help but they too can make beautiful paintings. You can use any paint you like , water colors , tempera, acrylic, it all depends on budget and students ages/experience with painting. These paintings not only test what students have learned but also gives them a creative way to express what they found most important about Native American Cultures.
