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 1.05
Use area or region models and set models of fractions to explore part-whole relationships.
  • Represent fractions concretely and symbolically (halves, fourths, thirds, sixths, eighths).
  • Compare and order fractions (halves, fourths, thirds, sixths, eighths) using models and benchmark numbers (zero, one-half, one); describe comparisons.
  • Model and describe common equivalents, especially relationships among halves, fourths, and eighths, and thirds and sixths.
  • Understand that the fractional relationships that occur between zero and one also occur between every two consecutive whole numbers.
  • Understand and use mixed numbers and their equivalent fraction forms.
