Third grade mathematics includes learning experiences with whole numbers through hundred thousands, fractions, the concepts of multiplication and division, measurement, geometry, and graphing. Activities which promote the development of problem-solving strategies, logical reasoning, and pattern analysis are important components of the program. Communicating mathematically and connecting mathematics to the real world are emphasized.
The third-grade standards place increasing emphasis on conducting investigations. Students are expected to be able to develop questions, formulate simple hypotheses, make predictions, gather data, make inferences, and draw conclusions. In the area of physical science, the standards focus on simple and compound machines, energy, and a basic understanding of matter. Behavioral and physical adaptations are examined in relation to the life needs of animals. The notion of living systems is further explored in aquatic and terrestrial food chains and diversity in ecosystems. Patterns in the natural world are demonstrated in terms of the phases of the moon, tides, seasonal changes, the water cycle, and animal and plant life cycles. Geological concepts are introduced through the investigation of the components of soil.
The standards for third-grade students include an introduction to the heritage and contributions of the people of ancient China, Egypt, Greece, Rome, and the West African empire of Mali. Students will continue developing map skills and will examine the social, cultural, and political characteristics of these major ancient world cultures. Students will recognize that many aspects of ancient cultures served as the foundation for modern governments, customs, traditions, and perspectives. Students will also demonstrate an understanding of basic economic and civics concepts throughout the year.
