Grade 7 Mathematics: AoPS-Aligned Curriculum
المسار: Education
A comprehensive Grade 7 mathematics course aligned to the Common Core State Standards and built from Art of Problem Solving (AoPS) resources. The course integrates Pre-Algebra, Introduction to Algebra, and Introduction to Geometry to develop deep conceptual understanding and problem-solving proficiency across The Number System, Ratios and Proportional Relationships, Expressions and Equations, Geometry, and Statistics & Probability.

1. Model real-world quantities with rational numbers using number lines and properties of operations to compute, justify, and evaluate results.
أهداف التعلم:
1. Compute and explain net change in bank balances, game scores, or elevations by adding and subtracting signed numbers on a number line.
2. Justify additive inverses by pairing opposite transactions (e.g., a $12 deposit vs. a $12 withdrawal) and explaining why the sum is zero.
3. Multiply and divide positive and negative rational numbers in contexts (such as rate conversions or scale changes) and defend the sign rules used.
4. Apply properties of operations and the order of operations to evaluate multi-step expressions with fractions and decimals in recipe scaling or construction measurements.
5. Convert between fractions, decimals, and percents in context (prices, measurements) and select the most efficient form for computation.
