Mathematical Process

  1. Geometric Prop - Make and testxer conjectures about geometric properties and develop logical arguments to justify conclusions.
  2. Estimation - Make reasonable estimates of fraction and decimal sums or differences using models.
  3. Rounding - Explore different methods of estimation including rounding and truncating.
  4. Remainders - Explore problems in different contexts to interpret the meaning of remainders as discrete values or not.
  5. Solve Problems - Solve problems in more than one way and explain why one process may be more effective than another.
  6. State Answers - Communicate answers in correct verbal and numerical form; including use of mixed numbers or fractions and use of units.
  7. Verbal - Organize and consolidate verbal statements involving fractions and mixed numbers into diagrams, symbols, and numerical expressions.
  8. Patterns - Use patterns, models, and relationships as contexts for writing inequalities and simple equations.
  9. Other Media - Use age-appropriate books, stories, and videos to convey ideas of mathematics.

Number and Operation

  1. Prime - Identify prime numbers up to 50.
  2. Use Prime Factorization - Use the prime factorization of two whole numbers to determine the greatest common factor and the least common multiple.
  3. Fractions and Decimals - Use visual models, benchmarks, and equivalent forms to add and subtract commonly used fractions and decimals.
  4. Factoring - Use divisibility rules to factor numbers.
  5. Estimation - Make reasonable estimates of fraction and decimal sums and differences.
  6. Mixed Numbers - Add and subtract mixed numbers.
  7. Decimal Point - Understand the placement of the decimal point in calculations of multiplication and long division, including the placement in the estimation of the answer.
  8. Division by Zero - Understand that division by zero is undefined.
  9. Negative Numbers - Explore numbers less than 0 by extending the number line through familiar applications (e.g., temperatures below zero, owing money, measuring elevation below sea level).
  10. Exponential Notation - Use exponential notation to represent repeated multiplication of whole numbers.
