Due to the fact that Mexico is a close neighbor of ours and more Mexican people are coming into our neighborhoods, I felt like students needed to be aware fo backgrounds involved. This unit was chosen because it helped students realize that everyone lives in an environment and that people need shelter according to culture and environment. The Tennessee Curriculum Standard History K-2 states that students will exhibit an understanding of the dynamic interaction between human and physical systems around the world. This unit let the students realize and see the many similarities and differences between families in Mexico and their own families.
