# Number and Operation in Base Ten

## Narrative for the (NBT) Number and Operation in Base Ten

At Grade 4, students extend their work in the base-ten system. They use standard algorithms to fluently add and subtract. They use methods based on place value and properties of operations supported by suitable representations to multiply and divide with multi-digit numbers. Visual representations such as area and array diagrams that students draw and connect to equations and other written numerical work are useful for this purpose. By reasoning repeatedly about the connection between math drawings and written numerical work, students can come to see multiplication and division algorithms as abbreviations or summaries of their reasoning about quantities.

Building on earlier work, students generalize place value understanding for multi-digit whole numbers to read, write, and compare whole numerals between 1,000 and 1,000,000. They also extend understanding of place value to include decimals to hundredths and fractional quantities 1/10 and 1/100.

 MAT-04 Targeted Standards(NBT) Domain: Number and Operations in Base TenCluster: Generalize place value understanding for multi­digit whole numbers. Limited to whole numbers less than or equal to 1,000,000. MAT-04.NBT.01 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
