In fourth grade children take on new types of work and social experiences. Fourth graders learn to collaborate with their peers on group projects. They need to know how to manage their work more independently. Books, books, and more books fill the curriculum as fourth graders become sophisticated readers. Teachers introduce genres such as myths and legends, fantasy and adventure and more. Fourth graders relate characters and other story elements to their own lives, and empathize with the characters most like them. Most importantly, they learn to organize information into paragraphs, essays, projects, and presentations that help students synthesize their learning. In Math, fourth graders read, write, compare, add, subtract, multiply, and divide with very large whole numbers. They do more equations with fractions and decimals; and learn about prime and composite numbers. They solve problems about factors and multiples, and explore geometry formulas for determining perimeter and area, and for measuring angles. Fourth grade Scientists look at changes in the Earth over long periods of time, observing the water cycle, or understanding the interactions between organisms and their environment. Students work on projects that ask them to build hypotheses and make predictions. Science topics include: matter and its different states, forms of energy, and the solar system. Fourth Grade Historians are exposed to the first people to live in their area, explore changes in state populations over time, and how different people and cultures have adapted to, and influenced the state. They'll learn how their state fits into a particular region of the country. Local, state and federal government structure will be introduced, and students will learn about the government offices responsible for making, enforcing, and interpreting state laws.
