4.NBT.2 - About the Math, Learning Targets, and Rigor

Grade 4 Whole Numbers

4.NBT.2

Full Standard

Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.

Learning Targets

  • Read and write a number in word form and standard form.
  • Compose and decompose numbers using expanded form and alternatives (i.e. 746 can be decomposed by place value as 700 + 40 + 6. It can also be decomposed as 700 + 46, 600 + 146, 500 + 246, 699 + 56, etc).
  • Compare numbers using place value and symbols.

 

About the Math

Numbers can be represented in various ways. Representations are related. Three forms used in 4th grade include:

Place Value Dice

Standard Form: 463,732
Word Form: Four-hundred-sixty-three thousand, seven-hundred-thirty-two. DO not say AND in between the tens and ones digits. AND is said as the decimal point.
Expanded Form: 400,000 + 60,000 + 3,000 + 700 + 30 + 2

  • Read and write a number in word form and standard form.

Standard form is the form in which we most frequently interact with a number. Students have worked with numbers in standard form since kindergarten. The same is true for word form. Word form is the representation of a number with words. The most frequent use of this form is likely writing checks. 

  • Compose and decompose numbers using expanded form and alternatives (i.e. 746 can be decomposed by place value as 700 + 40 + 6. It can also be decomposed as 700 + 46, 600 + 146, 500 + 246, 699 + 56, etc).

Numbers can be composed in various ways. Expanded form is a recognized way for composing a number. Expanded form has many applications. In grade 4, students leverage it for partial sums and partial products. Numbers can be decomposed in other ways as well. Decomposing numbers in varied ways helps support number sense and computational fluency. Note that expanded form can be written as follows: 3 x 100 + 2 x 10 + 6 for 326, however this is not an expectation at the 4th-grade level.

  • Compare numbers using place value and symbols.

Numbers can be compared through a variety of strategies. Basic and expected comparisons are done via the comparison number of place values and the digit in place values. Students should also reason about comparison using number lines and other place value models. It is wise to incorporate estimation into conversations and lessons about comparison.

Important vocabulary for this standard includes standard form, expanded form, and word form.
