In this lesson, the final one in a series, students play games that require multiplication skills and take part in diagnostic interviews. Reasoning is the process standard applied in this lesson. During the games, students will practice the multiplication facts in the 6 and 7 tables, identify the facts they have left to memorize, and employ strategies to help them memorize the remaining multiplication facts. Once they understand the effects of multiplying and dividing whole numbers, students will select appropriate methods and tools for computing with whole numbers from among mental computation, estimation, calculators, and paper and pencil according to the context and nature of the computation and use the selected method or tools. NCTM provides several helpful resources for teachers to implement this lesson.

Grade 3

  • Goal 1: Number and Operations - The learner will model, identify, and compute with whole numbers through 9,999.
    • Objective 1.01: Develop number sense for whole numbers through 9,999.
      • Connect model, number word, and number using a variety of representations.
      • Build understanding of place value (ones through thousands).
      • Compare and order.
    • Objective 1.03: Develop fluency with multiplication from 1x1 to 12x12 and division up to two-digit by one-digit numbers using:
