Grade 2 Mathematics
This course guides second grade students through the development of flexible number sense and logical reasoning. Students move beyond rote memorization to explore the relationships between quantities, shapes, and data through collaborative problem solving.
Number Sense and Place Value Patterns
Students explore the power of the base ten system and learn to decompose numbers up to 1000.
Understanding how digits change value based on their position within a number.
Developing strategies to determine the relative magnitude of numbers using relational symbols.
Identifying patterns in sequences to build a foundation for multiplication and mental math.
Additive Thinking and Mental Strategies
Focusing on the relationship between addition and subtraction and the development of flexible computation strategies.
Exploring how addition and subtraction undo each other within fact families.
Moving beyond counting on fingers to using doubling, making tens, and compensation.
Breaking down complex word problems into manageable mathematical steps.
Geometry and Spatial Reasoning
Investigating the properties of 2D shapes and 3D objects and how they fit together in space.
Identifying and classifying shapes based on sides, vertices, and angles.
Combining smaller shapes to create new ones and partitioning wholes into equal shares.
Connecting abstract geometric solids to everyday objects and their functional properties.
Measurement and Data Literacy
Using standard units to quantify the world and organizing information to make decisions.
Exploring why universal units like centimeters and meters are necessary for clear communication.
Reading analog clocks and understanding the cyclical nature of time.
Collecting survey data and creating graphs to reveal trends and answer questions.
