# Number and Operations in Base Ten (NBT)

Note: Grade 4 expectations in this domain are limited to whole numbers less than or equal to 1,000,000.

• 4.NBT.A  Generalize place value understanding for multi-digit whole numbers.
• 4.NBT.A.1  Apply concepts of place value, multiplication, and division to understand that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.
• 4.NBT.A.2  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.
• 4.NBT.A.3  Use place value understanding to round multi-digit whole numbers to any place.
• 4.NBT.B  Use place value understanding and properties of operations to perform multi-digit arithmetic.
• 4.NBT.B.4  Fluently add and subtract multi-digit whole numbers using a standard algorithm.
• 4.NBT.B.5  Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
• 4.NBT.B.6  Demonstrate understanding of division by finding whole-number quotients and remainders with up to four-digit dividends and one-digit divisors.
