During this lesson, students use the mathematical knowledge and skills developed in the previous lessons to demonstrate understanding and ability to apply that knowledge to playing a domino game. After the students name the models used during the unit, they illustrate, with a domino, the addition properties they explored. Then, in pairs, students practice the facts they need to learn.

Students will be able to:

  • Review the models for addition.
  • Use the properties of addition.
  • Memorize the addition facts.

NCTM Standards and Expectations covered in this lesson include:

  • Developing a sense of whole numbers and representing and using them in flexible ways, including relating, composing, and decomposing numbers.
  • Counting with understanding and recognizing “how many” in sets of objects.
  • Developing understanding of the relative position and magnitude of whole numbers and of ordinal and cardinal numbers and their connections.
  • Using multiple models to develop initial understandings of place value and the base-ten number system.
  • Understanding the effects of adding and subtracting whole numbers.
  • Understanding various meanings of addition and subtraction of whole numbers and the relationship between the two operations.
  • Developing and using strategies for whole-number computations, with a focus on addition and subtraction.
  • Using a variety of methods and tools to compute, including objects, mental computation, estimation, paper and pencil, and calculators.
  • Developing fluency with basic number combinations for addition and subtraction.

      • Read and write numbers.
      • Compare and order sets and numbers.
      • Build understanding of place value (ones, tens).
      • Estimate quantities fewer than or equal to 100.
      • Recognize equivalence in sets and numbers 1-99.
    • Objective 1.03: Develop fluency with single-digit addition and corresponding differences using strategies such as modeling, composing and decomposing quantities, using doubles, and making tens.
