5th Grade MULTIPLICATION Standards


5.1 Mathematical process standards. The student uses mathematical processes to acquire and demonstrate mathematical understanding. The student is expected to:

  • B. Use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution.
  • C. Select tools, including real objects, manipulatives, paper and pencil, and technology as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems.
  • D. Communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate.
  • E. Create and use representations to organize, record, and communicate mathematical ideas.
  • F. Analyze mathematical relationships to connect and communicate mathematical ideas.
  • G. Display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication.

5.4 Algebraic reasoning. The student applies mathematical process standards to develop concepts of expressions and equations. The student is expected to:

  • A. Identify prime and composite numbers; Supporting Standard.
  • E. Describe the meaning of parentheses and brackets in a numeric expression; Supporting Standard.

Common Core

Operations & Algebraic Thinking:
Write and interpret numerical expressions.

  • 5.OA.A.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
  • 5.OA.A.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation "add 8 and 7, then multiply by 2" as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.

Number & Operations ­- Fractions:
Apply and extend previous understandings of multiplication and division.

  • 5.NF.B.5 Interpret multiplication as scaling (resizing), by:
    • 5.NF.B.5.A Comparing the size of a product to the size of one factor on the basis of the
      size of the other factor, without performing the indicated multiplication.
