Building sets of 19 and 20

Mathematics (2004)

Grade 1

• Goal 1: Number and Operations - The learner will read, write, and model whole numbers through 99 and compute with whole numbers.
  • Objective 1.01: Develop number sense for whole numbers through 99.
    • Connect the model, number word, and number using a variety of representations.
    • Use efficient strategies to count the number of objects in a set.
    • 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.

Grade 2

• Goal 1: Number and Operations - The learner will read, write, model, and compute with whole numbers through 999.
  • Objective 1.01: Develop number sense for whole numbers through 999.
    • Connect model, number word, and number using a variety of representations.
    • Read and write numbers.
    • Compare and order.
    • Rename.
    • Estimate.
    • Use a variety of models to build understanding of place value (ones, tens, hundreds).
  • Objective 1.05: Create and solve problems using strategies such as modeling, composing and decomposing quantities, using doubles, and making tens and hundreds.

Kindergarten

• Goal 1: Number and Operations - The learner will recognize, model, and write whole numbers through 30.
  • Objective 1.01: Develop number sense for whole numbers through 30.
    • Connect model, number word (orally), and number, using a variety of representations.
    • Count objects in a set.
    • Read and write numerals.
    • Compare and order sets and numbers.
    • Use ordinals (1st-10th).
    • Estimate quantities fewer than or equal to 10.
    • Recognize equivalence in sets and numbers 1-10.
