Grade 1 Mathematics
This course builds a deep understanding of number relationships and spatial reasoning through hands-on exploration. Students move beyond rote memorization to develop flexible problem solving strategies using concrete materials and visual representations.
Number Sense and Quantity
Students explore the meaning of numbers up to 100, focusing on counting patterns and the relationship between quantities.
Developing the ability to recognize small groups of objects without counting and using benchmarks like five and ten.
Exploring skip counting by 2s, 5s, and 10s to understand the structure of the hundred chart.
Using mathematical language to describe the relationship between different magnitudes.
Operations and Algebraic Thinking
Students develop mental math strategies for addition and subtraction while exploring the concept of equality.
Moving from counting on fingers to using derived facts like doubles and making ten.
Reframing the equal sign as a symbol of balance rather than an instruction to find an answer.
Translating real world scenarios into mathematical expressions using drawings and symbols.
Geometry and Spatial Reasoning
Students identify, describe, and compose geometric shapes while exploring their attributes.
Distinguishing between defining attributes like sides and non defining attributes like color or size.
Combining smaller shapes to create new composite shapes and identifying parts of a whole.
Using precise language to describe the location and movement of objects in space.
Measurement and Data Literacy
Students learn to measure length and time while using data to answer questions about their community.
Measuring objects using non standard units and comparing lengths indirectly.
Reading clocks to the hour and half hour and understanding the duration of events.
Organizing information into charts and graphs to identify trends and answer questions.
