Math
In Second Grade Math, students have the opportunity to investigate and develop skills involving numbers, measurement, geometry, patterns, and data analysis.

Numbers
Students demonstrate number sense, including an understanding of number systems and operations and how they relate to one another. Students computefluently and make reasonable estimates using paper and pencil, technology supportedand mental methods.

Measurement
Students estimate and measure to a required degree of accuracy and precision by selecting and using appropriate units, tools and technologies.

Geometry
Students identify, classify, compare and analyze characteristics, properties and relationships of one-, two- and three-dimensional geometric figures and objects. Students use spatial reasoning and properties of geometric objects to analyze mathematical situations and solve problems.

Patterns
Students extend simple number patterns; use patterns to make generalizations and predictions; and create new patterns with consistent rules or plan. They use objects, pictures, numbers and other symbols to represent a problem situation. They understand equivalence and extend the concept to symbols. They use symbols to represent unknown quantities and identify values for symbols in an expression or equation using addition and subtraction. They describe qualitative and quantitative changes, especially those involving addition and subtraction.

Data Analysis
Students pose questions and collect, organize, represent, interpret and analyze data to answer questions. Students read, interpret and make comparisons and predictions from data. They use mathematical processes and knowledge to solve problems. Students apply problem-solving and decision-making techniques, and communicate mathematical ideas. (back)
