In this Science NetLinks lesson, students will work with manipulatives (beans) to create and solve math problems, some of which have more than one correct answer. This lesson addresses the common misconception that there is only one correct way to solve any math problem.

Mathematics (2004)

Grade 3

  • Goal 1: Number and Operations - The learner will model, identify, and compute with whole numbers through 9,999.
    • Objective 1.06: Develop flexibility in solving problems by selecting strategies and using mental computation, estimation, calculators or computers, and paper and pencil.
  • Goal 5: Algebra - The learner will recognize, determine, and represent patterns and simple mathematical relationships.
    • Objective 5.02: Extend and find missing terms of repeating and growing patterns.
    • Objective 5.03: Use symbols to represent unknown quantities in number sentences.
    • Objective 5.04: Find the value of the unknown in a number sentence.

Grade 4

  • Goal 1: Number and Operations - The learner will read, write, model, and compute with non-negative rational numbers.
    • Objective 1.05: Develop flexibility in solving problems by selecting strategies and using mental computation, estimation, calculators or computers, and paper and pencil.
  • Goal 5: Algebra - The learner will demonstrate an understanding of mathematical relationships.
    • Objective 5.01: Identify, describe, and generalize relationships in which:
      • Quantities change proportionally.
      • Change in one quantity relates to change in a second quantity.
    • Objective 5.02: Translate among symbolic, numeric, verbal, and pictorial representations of number relationships.
    • Objective 5.03: Verify mathematical relationships using:
      • Models, words, and numbers.
      • Order of operations and the identity, commutative, associative, and distributive properties.
