Expectations

  • K.NR.1.1

    Count up to 20 objects in a variety of structured arrangements and up to 10 objects in a scattered arrangement.

  • K.NR.1.2

    When counting objects, explain that the last number counted represents the total quantity in a set (cardinality), regardless of the arrangement and order.

  • K.NR.1.3

    Given a number from 1-20, identify the number that is one more or one less.

  • K.NR.1.4

    Identify pennies, nickels, and dimes and know their name and value.

The same standard across grades

  1. Kindergarten · K.NR.1 (this standard)

    Demonstrate and explain the relationship between numbers and quantities up to 20; connect counting to cardinality (the last number counted represents the total quantity in a set).

  2. Grade 1 · 1.NR.1

    Extend the count sequence to 120. Read, write, and represent numerical values to 120 and compare numerical values to 100.

  3. Grade 2 · 2.NR.1

    Using the place value structure, explore the count sequences to represent, read, write, and compare numerical values to 1000 and describe basic place-value relationships and structures.

  4. Grade 3 · 3.NR.1

    Use place value reasoning to represent, read, write, and compare numerical values up to 10,000 and round whole numbers up to 1,000.

  5. Grade 4 · 4.NR.1

    Recognize patterns within the base ten place value system with quantities presented in real-life situations to compare and round multi-digit whole numbers through the hundred-thousands place and compare decimal numbers to the hundredths place.

  6. Grade 5 · 5.NR.1

    Use place value understanding to solve real-life, mathematical problems.

  7. Grade 6 · 6.NR.1

    Solve relevant, mathematical problems involving operations with whole numbers, fractions, and decimal numbers.

  8. Grade 7 · 7.NR.1

    Solve relevant, mathematical problems, including multi-step problems, involving the four operations with rational numbers and quantities in any form (integers, percentages, fractions, and decimal numbers).

  9. Grade 8 · 8.NR.1

    Solve problems involving irrational numbers and rational approximations of irrational numbers to explain realistic applications.
