Students use concepts and themes such as system, change, scale, and model to help them understand and explain the natural world. In other words, students understand the natural world more meaningfully when they use concepts and themes to make the connections between objects, events, and experiences. For example, in studying the unifying concept of system, as in ecosystem, students make connections between the physical and biological factors that affect mango yield. Mango yield is dependent on temperature, wind, water, and length of day and pollinators. Students analyze properties of objects and relationships among the properties.
Students use transformations and symmetry to analyze mathematical situations.
Students select and use different representational systems, including coordinate geometry. Function Investigator Equivalent Linear Equations Use degree measures in problem situations. Students understand numbers, ways of representing numbers, relationships among numbers, and number systems. Matrix Analyzer Matrices and Data Recognize and use real and complex numbers and infinity. Students understand the meaning of operations and how they relate to each other.
