2nd Class Mathematical Explorers: Building Foundations
A comprehensive second class mathematics curriculum focusing on developing fluency with numbers up to 200, spatial reasoning, and logical problem solving. Students engage in hands on activities to bridge the gap between concrete manipulation and abstract mathematical thinking.

Number Power and Place Value
Students explore the base ten system to understand how numbers up to 200 are constructed and compared.
Grouping units into tens and tens into hundreds to understand place value positions.
Using symbols and logic to determine the relationship between different numerical values.
Identifying visual and numerical patterns within a 100 or 200 grid.

Operations and Algebraic Thinking
Developing flexible strategies for addition and subtraction while exploring the relationship between the two.
Moving from counting on to using doubles, near doubles, and bridging through ten.
Understanding subtraction not just as taking away, but as finding the gap between two numbers.
Applying operations to word problems and everyday scenarios.

Shape, Space, and Symmetry
Investigating the properties of 2D and 3D shapes and how they interact in space.
Identifying and classifying 3D shapes based on faces, edges, and vertices.
Examining the attributes of flat shapes and their relationship to 3D surfaces.
Discovering balance in shapes and how they move through flips, slides, and turns.

Measuring Our World
Using standard and non standard units to quantify length, weight, capacity, and time.
Transitioning from using hands and feet to using meters and centimeters.
Comparing the mass of objects and the volume of containers using kilograms and liters.
Reading clocks to the quarter hour and understanding the duration of events.

Data and Chance
Collecting information, representing it visually, and discussing the likelihood of events.
Using tally marks and tables to keep track of information gathered from the class.
Creating and reading simple graphs to answer questions about a data set.
Exploring the language of probability such as likely, unlikely, certain, and impossible.
