1.NR.1Count Sequence to 120

Expectations

• 1.NR.1.1

  Count within 120, forward and backward, starting at any number. In this range, read and write numerals and represent a number of objects with a written numeral.

• 1.NR.1.2

  Explain that the two digits of a 2-digit number represent the amounts of tens and ones.

• 1.NR.1.3

  Compare and order whole numbers up to 100 using concrete models, drawings, and the symbols >, =, and <.

Georgia Milestones coverage

No Georgia Milestones blueprint cites this standard.

The same standard across grades

1. Kindergarten · K.NR.1

   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 (this standard)

   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.
