* Grade 4 students work with whole numbers less than or equal to 1,000,000.
Vocabulary
Place Value: The value of a digit in a number
Digit: A symbol used to show a number
Estimate: An approximate calculation that is close to the exact number based on rounding
Compare: Tell how a number is related to another number using >, <, =, or different
Rounding: to find the nearest ten, hundred, or thousand (and so on). For example, 391 rounds up to 400 and 331 rounds up to 300.
Expanded Form: Writing a number as the sum of the values in each digit
Regrouping: To exchange amounts of equal value to rename a number
