My district reading curriculum is StoryTown. The 3rd grade series ends with two stories, one fiction and one nonfiction, about our solar system. It is a wonderful way to end of the school year. The students really get into learning more about space and each of the planets. Our writing for these two weeks is a research project over each planet. Students are placed in groups of two or three and assigned a planet to study.
Because it is the end of the school year and I will be moving classrooms, my bulletin boards are down. So we created a new bulletin board with the planets lined at the top and the inside of our space ship at the bottom. We filled the space with stars and comets as well.
