3: Grade 3

Grade 3 centers on three strands. Data and Probability deepens statistical questioning, data collection methods, data visualization analysis, and introduces probability language. Spatial Reasoning develops fractional precision measurement, unit comparison across systems, perimeter calculation, money change, and polygon construction. Patterns and Relationships builds place value to 100,000, extends addition and subtraction to 1,000, introduces multiplication and division within 144, develops fraction concepts through eighths, begins equivalent fractions, and introduces algebraic properties and input-output rules.
